+Now we'll explore Spack Environments, a powerful feature that lets us manage collections of packages together in a documented and reproducible way.
 Spack environments are similar to *virtual environments* in other package managers (e.g., `Python venv <https://docs.python.org/3/library/venv.html>`_, `Conda Environments <https://docs.conda.io/projects/conda/en/stable/user-guide/getting-started.html>`_, or `nix-env <https://nix.dev/manual/nix/2.24/command-ref/nix-env>`_).
 
--------------------------------
-What Makes a Spack Environment?
--------------------------------
+Managing a software stack with many packages and varying configuration can quickly become hard to track by hand.
+An environment lets you:
 
-Spack environments are based around two key files that can be easily shared and reused across different systems:
+* Establish a standard set of requirements for a project,
+* Install and use them together as a unit,
+* Reproduce the same build on another machine, and
+* Document your software stack for collaborators, CI/CD pipelines, and releases.
 
-* ``spack.yaml`` -- The main configuration file where we specify which packages to install, compilers to use, and other Spack settings.
+Each environment is captured in two shareable files: ``spack.yaml`` records the requested specs and configuration, while ``spack.lock`` captures the fully concrete build for reproducibility.
+We'll look at both in detail later in this tutorial.
 
-* ``spack.lock`` -- A lockfile that captures the complete provenance of your environment, enabling reproduction of software environments.
 
----------------------
-Why Use Environments?
----------------------
-
-Managing complex software setups with multiple packages and varying configuration (like different MPI) can quickly become overwhelming.
-Spack environments solve this by letting you:
-
-* Establish standard software requirements for your project(s)
-* Set up consistent runtime environments for your users
-* Maintain reproducible development environments
-* Configure packages for CI/CD pipelines
-* Share and reproduce builds across different machines
-* Document your software stack for collaboration
-* And much more
-

-Goals of this Tutorial

-
-This tutorial will teach you the fundamentals of creating and using Spack environments.

-We'll cover:
-
-1. Command line basics -- Creating and managing environments with Spack commands.
-
-2. Configuration files -- Editing ``spack.yaml`` and understanding ``spack.lock``.
-
-3. Environment types -- Understanding Spack-managed vs. independent environments.

+Now that we understand how creation and activation work, let's go back to our ``myproject`` environment and install a couple of packages, specifically ``tcl`` and ``trilinos``.
 
-Let's try the usual install commands we learned earlier:
+Installing software in an environment follows three steps:
 
-.. literalinclude:: outputs/environments/env-fail-install-1.out
-   :language: spec
+1. **add** the specs we want, registering them as *root specs* of the environment;
+2. **concretize** the environment, resolving every root and its dependencies into a concrete set; and
+3. **install** the concretized specs.
 
-Environments are special in that we must *add* specs to the an environment before we can install them.
-This additional step helps prevent us from accidentally modifying a shared environment when installing new software.
+We'll walk through them one at a time.
 
-``spack add`` allows us to queue up several specs to be installed together.
-Let's try it:
+First, we *add* our two specs with ``spack add``:
 
 .. literalinclude:: outputs/environments/env-add-1.out
-   :language: spec
-
-Now, ``tcl`` and ``trilinos`` have been registered as **root specs** in our environment.
-**Root specs** are packages that we've explicitly requested to be installed in an environment.
-
-They're called **"roots"** because they sit at the top of the dependency graph---when Spack installs these packages, with their respective dependency packages sitting below them.
-
-Now, let's install:
-
-.. literalinclude:: outputs/environments/env-install-1.out
    :language: console
 
-We can see that Spack reused existing installations of ``tcl`` and the dependencies of ``trilinos`` that were already present on the system, rather than rebuilding them from scratch.
-
-Additionally, the environment's view was automatically updated to include the installations.
-This means all the software in this environment has been added to our PATH, making the installed packages readily accessible from the command line while we have the environment activated.
+``tcl`` and ``trilinos`` are now registered as **root specs** i.e. the packages we've explicitly requested.
+They're called **"roots"** because they sit at the top of the dependency graph, with their dependency packages sitting below them.
 
-Let's now confirm the contents of the environment using ``spack find``:
+If we run ``spack find`` now, it lists them as roots but reports nothing concretized yet.
+Adding a spec only records our intent:
 
-.. literalinclude:: outputs/environments/find-env-2.out
+.. literalinclude:: outputs/environments/env-add-find-1.out
    :language: console
 
-We can see that the roots and all their dependencies have been installed.
+Next, we *concretize* the environment, resolving those roots and all their dependencies into a concrete set:
 
-^^^^^^^^^^^^^^
-Using Packages
-^^^^^^^^^^^^^^
-
-Spack environments provide a convenient way to use your installed packages by automatically making them available in your shell environment.
-This is accomplished through a feature called **environment views**.
-
-An environment view is a directory structure mirroring a standard Linux root filesystem with directories like ``/bin`` and ``/usr`` that contain symbolic links to all the packages installed in your Spack environment.
-When you activate an environment with ``spack env activate``, Spack automatically:
-
-* Prepends the view's ``bin`` directory to your ``PATH`` environment variable
-* Adds the view's ``man`` directory to your ``MANPATH`` for manual pages
-* Updates ``CMAKE_PREFIX_PATH`` to include the view's root directory
-
-This means that executables, libraries, and other files from your environment's packages become immediately accessible from your command line, just as if they were installed system-wide.
-
-Let's explore how views work using the ``tcl`` package we just installed in our ``myproject`` environment.
-The Tcl package includes a shell-like application called ``tclsh``.
-
-To see the path to ``tclsh`` let's use the ``which`` command:
-
-.. literalinclude:: outputs/environments/use-tcl-1.out
+.. literalinclude:: outputs/environments/env-concretize-1.out
    :language: console
 
+The ``spack find`` above hinted at this with *show with* ``spack find -c``.
+Now that the environment is concretized, that command lists the concrete set, including the packages still to be installed:
 
-Notice its path includes the name of our environment *and* a ``view`` subdirectory.
-
-We can now run ``tclsh`` just like you would any other program that is in your path:
-
-.. code-block:: console
-
-    $ tclsh
-    % echo "hello world!"
-    hello world!
-    % exit
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Removing Packages from Environments
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-One of Spack's key features is that you can safely remove packages from specific environments without affecting other environments.
-This works because Spack environments only create links to shared package installations---they don't contain the actual package files.
-
-Let's demonstrate this capability by creating a second environment.
-Imagine we have two projects:
-
-* ``myproject`` - requires ``trilinos``
-* ``myproject2`` - previously needed ``trilinos`` but no longer requires it
-
-Let's start by creating the ``myproject2`` environment and installing both ``scr`` and ``trilinos``:
-
-.. literalinclude:: outputs/environments/env-create-2.out
-   :language: spec
-
-
-Now we have two environments with different package combinations:
-
-* The ``myproject`` environment contains ``tcl`` and ``trilinos``
-* The ``myproject2`` environment contains ``scr`` and ``trilinos``
-
-Now let's attempt to uninstall ``trilinos`` from ``myproject2`` and examine what happens:
-
-.. literalinclude:: outputs/environments/env-uninstall-1.out
-   :language: spec
-
-
-Notice that ``trilinos`` won't be uninstalled because it's still referenced in ``myproject``.
-This safety feature prevents accidental removal of packages that other environments depend on.
-
-Instead, if we want to remove ``trilinos`` from the ``myproject2`` environment (without affecting it in other environments), we need to use ``spack remove``:
-
-.. literalinclude:: outputs/environments/env-remove-1.out
+.. literalinclude:: outputs/environments/env-find-c-1.out
    :language: console
 
-After running ``spack remove`` we'll see that ``trilinos`` is no longer a root but is still present in the installed specs.
-Reconcretizing the environment, we'll see the vestigial ``trilinos`` and its dependencies will be pruned and will no longer be listed in the environment at all.
+Finally, we *install*:
 
-We know ``trilinos`` is still needed for the ``myproject`` environment, so let's switch back to that environment to confirm that it is still installed.
-
-.. literalinclude:: outputs/environments/env-swap-1.out
+.. literalinclude:: outputs/environments/env-install-1.out
    :language: console
 
+We can see that Spack reused existing installations of ``tcl`` and the dependencies of ``trilinos`` that were already present on the system, rather than rebuilding them from scratch.
+Additionally, the environment's view was automatically updated to include the installations.
+This means all the software in this environment has been added to our PATH, making the installed packages readily accessible from the command line while we have the environment activated.
 
-Phew!
-We can see that ``myproject`` still has ``trilinos`` as a root spec.
-
-.. note::
-
-   You can also uninstall a package and remove it from the environment in one go with ``spack uninstall --remove trilinos``.
-
------------------------
-The ``spack.yaml`` file
------------------------
-
-An environment is more than just a list of root specs --- it includes **configuration settings** that control how Spack behaves when the environment it activated.
-So far, ``myproject`` relies on configuration defaults, but these can be overridden to customize our environment's behavior.
-
-In this section, we'll learn how to enforce that all the packages in our environment depending on ``mpi`` build with ``mpich`` by modifying our configuration.
-
-We can customize the selection of the ``mpi`` provider using `concretization preferences <https://spack.readthedocs.io/en/latest/build_settings.html#concretization-preferences>`_ to change the behavior of the concretizer.
-
-Let's start by examining our environment's configuration using ``spack config edit``:
-
-.. literalinclude:: outputs/environments/config-get-1.out
-
-The output shows the special ``spack.yaml`` configuration file that Spack uses to store environment configurations.
-
-There are several important parts of this file:
-
-* ``specs:`` The list of package specs to install in the environment.
-* ``view:`` Controls whether the environment generates a *view* (the directory tree with symlinks to installed packages we discussed earlier).
-* ``concretizer:unify:`` Determines how package specs in the environment are concretized together to reduce duplicated dependencies when possible.
-
-The ``specs`` list should look familiar --- these are the package specs we've been modifying previously with ``spack add`` and ``spack install``.
-
-The ``concretizer:unify:true`` setting controls how Spack resolves dependencies across packages specs in an environment:
-
-* ``true`` (default): specs are concretized *together*, ensuring there is only one version of each package in the environment.
-* ``false``: specs are concretized *independently* from each other, potentially allowing multiple versions of the package to appear in the environment twice.
-* ``when_possible``: A middle ground --- Spack attempts to unify dependencies as possible but will backoff to allow duplicates when root specs require incompatible versions of dependencies.

-Editing environment configuration

-
-.. note::
-
-   Before proceeding, make sure your ``EDITOR`` environment variable is set to the path of your preferred text editor.
-
-Let's edit ``spack.yaml`` to *require* ``mpich`` as our ``mpi`` provider using ``spack config edit``.
-
-You should now have the above file open in your editor.
-Change it to include the ``packages:mpi:require`` entry below:

-.. note::
-
-   We introduce this here to show you how environment configuration can affect concretization.
-   Configuration options are covered in much more detail in the :ref:`configuration tutorial <configs-tutorial>`.
-
-
-We've only scratched the surface here by requiring a specific ``mpi`` provider for packages depending on ``mpi``.
-There are many other customizations you can make to an environment.
-Refer to the links at the end of this section for more information.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Re-concretizing the environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You may need to re-install packages in the environment after making significant changes to the configuration, such as changing virtual providers.
-This can be accomplished by forcing Spack to re-concretize the environment and re-install the specs.
-
-For example, the packages installed in our ``myproject`` environment are now out of sync with our new configuration since we already installed part of the environment with ``openmpi``.
-Suppose we want to install everything in ``myproject`` with ``mpich``.
-
-Let's run ``spack concretize --force`` (or ``-f`` in short) to make Spack re-concretize all the environment's specs:
+Let's confirm the contents of the environment using ``spack find``:
 
-.. literalinclude:: outputs/environments/concretize-f-1.out
+.. literalinclude:: outputs/environments/find-env-2.out
    :language: console
 
-
-All the specs are now concrete **and** ready to be installed with ``mpich`` as the MPI implementation.
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Creating an environment incrementally
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-We can also add and install specs to an environment incrementally.
-For example:
-
-.. code-block:: spec
-
-   $ spack install --add python
-   $ spack install --add py-numpy@1.20
-
-If we create environments incrementally, Spack ensures that already installed roots are not re-concretized.
-So, adding specs to an environment at a later point in time will not cause existing packages to rebuild.
-
-Adding and installing specs incrementally leads to greedy concretization, meaning that the environment may have different package versions compared to an environment created all at once.
-
-When you first install ``python`` in an environment, Spack will pick a recent version.
-
-
-.. literalinclude:: outputs/environments/incremental-1.out
-   :language: spec
-
-If you then add ``py-numpy``, it may be in conflict with the ``python`` version already installed, and fail to concretize.
-
-.. warning::
-
-   There is a known bug in Spack that causes this set of specs to take over an hour to concretize, so there is no need to run it for this tutorial.
-
-.. code-block:: spec
-
-   $ spack install --add py-numpy@1.20 2>&1 | tail -n1
-   internal_error("version weights must exist and be unique"). Couldn't concretize without changing the existing environment. If you are ok with changing it, try `spack concretize --force`. You could consider setting `concretizer:unify` to `when_possible` or `false` to allow multiple versions of some packages.
-
-The solution is to re-concretize the environment as a whole, which causes ``python`` to downgrade to a version compatible with ``py-numpy``:
-
-.. literalinclude:: outputs/environments/incremental-2.out
-   :language: spec
+We can see that the roots and their dependencies have been installed.
+The packages reported as *concretized packages to be installed* are build-only dependencies, which Spack skips when it installs from binaries.
 
 .. note::
-   There are other advantages to concretizing and installing an environment all at once:
-
-   * If you have a number of specs that can be installed together, adding them first and installing them together enables them to share dependencies and reduces total installation time.
 
-   * You can launch all builds in parallel by taking advantage of Spack's `install-level build parallelism <https://spack.readthedocs.io/en/latest/config_yaml.html#build-jobs>`_.
+   We walked through the three steps separately, but in practice ``spack install`` concretizes for you, so ``spack add`` followed by ``spack install`` is all you need.
+   You must still add a spec before installing it, which prevents you from accidentally changing a shared environment.
+   Adding all specs before installing also lets Spack concretize them together, so they share dependencies and can all build in parallel.

-Building in environments
-------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^
+Using installed packages
+^^^^^^^^^^^^^^^^^^^^^^^^
 
-Activated environments allow you to invoke any programs installed in them as if they were installed on the system.
-In this section, we will take advantage of that feature.
+Activating an environment adds all of its installed software to our shell search paths through a feature called *environment views*.
+A view is a directory tree of symlinks to all installed packages, structured like a standard Linux filesystem (``bin/``, ``lib/``, ``include/``, ...).
 
-Suppose you want to compile some MPI programs.
-We have an MPI implementation installed in our ``myproject2`` environment, so ``mpicc`` is available in our path.
-We can confirm this using ``which``:
+For example, ``tcl`` ships a shell called ``tclsh``.
+Activating ``myproject`` puts it on our ``PATH``:
 
-.. literalinclude:: outputs/environments/show-mpicc-1.out
+.. literalinclude:: outputs/environments/use-tcl-1.out
    :language: console
 
+Notice the path includes the environment name and a ``view`` subdirectory.
+With ``openmpi`` installed in ``myproject`` as a dependency of ``trilinos``, ``mpicc`` is also on our ``PATH``:
 
-As mentioned before, activating the environment sets a number of environment variables.
-That includes variables like ``PATH``, ``MANPATH``, and ``CMAKE_PREFIX_PATH``, which allows you to easily find package executables and libraries installed in the environment.
-
-Let's look specifically at path-related environment variables using ``env | grep PATH``:
-
-.. literalinclude:: outputs/environments/show-paths-1.out
+.. literalinclude:: outputs/environments/show-mpicc-1.out
    :language: console
 
-
-We can demonstrate use of these environment settings by building a really simple MPI program.
-
-Let's create a program called ``mpi-hello.c`` that contains the following code:
+This means we can compile code against the environment's packages without any manual ``-I`` or ``-L`` flags.
+Let's build a small program that uses both MPI and ``zlib``:

-Reproducing builds
-------------------
+.. literalinclude:: outputs/environments/show-paths-1.out
+   :language: console
 
-Spack environments provide users with *virtual environments* similar to `Python venv <https://docs.python.org/3/library/venv.html>`_ and `Conda environments <https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html>`__).
-The goal is to ensure packages in one environment are kept separate from those of another.
-These environments can be managed by Spack or independent.
-In either case, their environment files can be used to reproduce builds by other users and on other machines.
-Since those files are key to reproducing builds, let's start with them.
+we find ``CMAKE_PREFIX_PATH`` and ``PKG_CONFIG_PATH`` too, so build tools find the environment's libraries and headers automatically.
 
 ^^^^^^^^^^^^^^^^^
-Environment files
+Removing Packages
 ^^^^^^^^^^^^^^^^^
 
-There are two key files tracking the contents of environments: ``spack.yaml`` and ``spack.lock``.
-The ``spack.yaml`` file holds the environment configuration that we previously edited through ``spack config edit``.
-The ``spack.lock`` file is automatically generated during concretization.
+Spack offers two ways to get rid of a package in an environment:
+
+* ``spack remove`` takes a spec *out of the environment*
+* ``spack uninstall`` deletes the installed files *from disk*
 
-The two files represent two fundamental concepts:
+In a setup with several environments these behave quite differently, so let's create a second environment to see how.
+We'll create ``myproject2``, activate it, and add both ``scr`` and ``trilinos``:
 
-* ``spack.yaml``: *abstract* specs and configuration to install; and
-* ``spack.lock``: all fully *concrete* specs.
+.. literalinclude:: outputs/environments/env-create-2.out
+   :language: console
 
+then concretize and install as usual:
 
-These files are intended to be used by developers and administrators to manage the environments in a reproducible way.
-We will cover their reuse later.
+.. code-block:: console
 
-.. note::
+   $ spack concretize
+   $ spack install
 
-   Both environment files can be versioned in repositories, shared, and used to install the same set of software by different users and on other machines.
+``spack find`` lets us confirm the environment now holds both roots and their dependencies:
 
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Managed versus independent environments
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+.. literalinclude:: outputs/environments/env-create-2-find.out
+   :language: console
 
-Environments are either Spack-managed or independent.
-Both types of environments are defined by their environment files.
-So far, we have only created managed environments.
-This section describes their differences.
+So ``myproject`` contains ``tcl`` and ``trilinos``, while ``myproject2`` contains ``scr`` and ``trilinos``.
 
-*Managed environments* are created using ``spack env create <name>``.
-They are automatically created in the ``var/spack/environments`` subdirectory and can be referenced by their names.
+Let's start with the simplest case.
+``scr`` is used only by ``myproject2``, so we can remove it cleanly.
+``spack remove`` is the counterpart to ``spack add``: it drops ``scr`` as a root spec.
 
-*Independent environments* can be created in one of two ways.
-First, the Spack environment file(s) can be placed in any directory (other than ``var/spack/environments``).
-Alternatively, you can use ``spack env create -d <directory>`` to specify the directory (``<directory>``) in which the files should reside.
-Independent environments are not named.
+.. literalinclude:: outputs/environments/env-remove-scr-1.out
+   :language: console
 
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Reviewing a managed environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+That only updates the environment's configuration, though.
+Right afterward, ``spack find`` still lists ``scr``.
+It is no longer a root, but it is still part of the environment:
 
-We created the ``myproject`` environment earlier using ``spack env create myproject`` so let's mainly focus on its environment files in this section.
+.. literalinclude:: outputs/environments/env-remove-scr-2.out
+   :language: console
 
-Earlier, when we changed the environment's configuration using ``spack config edit``, we were actually editing its ``spack.yaml`` file.
-We can move to the directory containing the file using ``spack cd``:
+To actually drop it, we reconcretize the environment:
 
-.. literalinclude:: outputs/environments/filenames-1.out
+.. literalinclude:: outputs/environments/env-remove-scr-3.out
    :language: console
 
+Now ``scr``, along with any dependencies nothing else needs, has been pruned, and ``spack find`` no longer lists it:
 
-Notice that ``myproject`` is a subdirectory of ``var/spack/environments`` within the Spack installation making it a *managed* environment.
-Consequently, it can be referenced by name.
-It will also show up when running ``spack env list``:
+.. literalinclude:: outputs/environments/env-remove-scr-4.out
+   :language: console
 
-.. literalinclude:: outputs/environments/env-list-2.out
+``trilinos`` is a more interesting case, because ``myproject`` uses it too.
+Environments only *point to* shared installations rather than owning the files, so Spack won't let us delete one out from under another environment.
+If we try to uninstall ``trilinos`` from ``myproject2``, Spack refuses, since ``myproject`` still references it:
+
+.. literalinclude:: outputs/environments/env-uninstall-1.out
    :language: console
 
-which indicates the active environment by highlighting it in green.
+As the error suggests, ``spack remove`` is the right tool: it takes ``trilinos`` out of ``myproject2`` without touching the shared installation.
 
-We can also see from the listing above that the current environment directory contains both of the environment files: ``spack.yaml`` and ``spack.lock``.
-This is because ``spack.lock`` was generated when we concretized the environment.
+.. literalinclude:: outputs/environments/env-remove-1.out
+   :language: console
 
-If we ``cat`` the ``spack.yaml`` file, we'll see the same specs and view options previously shown by ``spack config edit``:
+We know ``trilinos`` is still needed by ``myproject``, so let's switch back and confirm it's still there:
 
-.. literalinclude:: outputs/environments/cat-config-1.out
-   :language: spec
+.. literalinclude:: outputs/environments/env-swap-1.out
+   :language: console
 
+``myproject`` still has ``trilinos`` as a root spec.
 
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Creating an independent environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-Environments do not have to be created in or managed by a Spack instance.
-Rather, their environment files can be placed in any directory.
-This feature can be quite helpful for use cases such as environment-based software releases and CI/CD.
+.. _environments-on-disk:
 
-Let's create an *independent* environment from scratch for a simple project:
+--------------------
+Environments on disk
+--------------------
 
-.. literalinclude:: outputs/environments/independent-create-1.out
+We have been treating an environment as an abstraction, but it is really just a directory on disk.
+``spack cd -e`` takes us to ``myproject``'s directory:
+
+.. literalinclude:: outputs/environments/filenames-1.out
    :language: console
 
+Because we created ``myproject`` with ``spack env create <name>``, it lives under ``var/spack/environments`` inside the Spack installation.
+This is what makes it a *managed* environment: we can refer to it by name.
+Environments can also be *independent*, with their files placed in any directory of our choosing.
+
+The directory holds the two files that define the environment:
 
-Notice that the command shows Spack created the environment, updated the view, and printed the command needed to activate it.
-As we can see in the activation command, since the environment is independent, it must be referenced by its directory path.
+* ``spack.yaml``: the *manifest* file containing the abstract specs we asked for plus configuration settings.
+* ``spack.lock``: the *lockfile* contaning the concrete specs generated whenever the environment is concretized.
 
-Let's see what really happened with this command by listing the directory contents and looking at the configuration file:
+``spack.yaml`` is the human-readable file we have been editing indirectly with ``spack add`` and ``spack remove``:
 
-.. literalinclude:: outputs/environments/independent-create-2.out
+.. literalinclude:: outputs/environments/cat-config-1.out
    :language: spec
 
+The ``concretizer:unify: true`` setting ensures all specs in the environment share a single version of each dependency.
+``spack.lock`` records the fully concretized environment (every package, version, variant, and dependency) so the build can be reproduced exactly.
+It is machine-readable JSON:
+
+.. literalinclude:: outputs/environments/lockfile-1.out
+   :language: console
 
-Notice that Spack created a ``spack.yaml`` file in the *code* directory.
-Also note that the configuration file has an empty spec list (i.e., ``[]``).
-That list is intended to contain only the *root specs* of the environment.
+The full file runs to thousands of lines.
+A hidden ``.spack-env`` directory (not shown by ``ls``) sits alongside these files and holds Spack's bookkeeping, including the view we used earlier.
 
-We can confirm that it is not a managed environment by running ``spack env list``:
+Managed environments also appear by name in ``spack env list``, with the active one highlighted:
 
-.. literalinclude:: outputs/environments/env-list-3.out
+.. literalinclude:: outputs/environments/env-list-2.out
    :language: console
 
-and noting that the path does not appear in the output.
+We will come back to both files when we reproduce environments later.
+
+------------------------
+Configuring environments
+------------------------
 
-Now let's add some specs to the environment.
-Suppose your project depends on ``trilinos`` and ``openmpi``.
-Add these packages to the spec list using your favorite text editor.
-The dash syntax for a YAML list is used in our example.
-Your package should now contain the following entries:
+We've seen ``spack.yaml`` contains the root specs of the environment.
+It also controls **configuration settings** that shape how Spack behaves when the environment is used.
+
+Let's edit ``spack.yaml`` to *require* ``mpich`` as our ``mpi`` provider using ``spack config edit`` (make sure ``EDITOR`` is set first).
+You should now have ``spack.yaml`` open in your editor.
+Change it to include the ``packages:mpi:require`` entry below:
 
 .. code-block:: yaml
+   :emphasize-lines: 6-8
 
    # This is a Spack Environment file.
    #
    # It describes a set of packages to be installed, along with
    # configuration settings.
    spack:
+     packages:
+       mpi:
+         require: [mpich]
+
      # add package specs to the `specs` list
      specs:
+     - tcl
      - trilinos
-     - openmpi
-     view: true
-     concretizer:
-       unify: true
 
-Now activate the environment and install the packages:
+The environment is now out of sync: ``myproject`` was installed with ``openmpi``, but the configuration now requires ``mpich``.
+If we run ``spack concretize``, Spack sees the existing concretization is still valid and does nothing:
 
-.. literalinclude:: outputs/environments/install-independent-1.out
+.. literalinclude:: outputs/environments/concretize-1.out
    :language: console
 
+To force Spack to re-concretize from scratch, use ``spack concretize --force``:
 
-Notice that Spack concretized the specs before installing them and their dependencies.
-It also updated the environment's view.
-Since we already installed all these packages outside of the environment, their links were simply added to the view.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Updating an installed environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Spack supports tweaking an environment even after the initial specs are installed.
-You are free to add and remove specs just as you would outside of the environment using the command line interface as before.
-
-For example, let's add ``hdf5`` and look at our file:
-
-.. literalinclude:: outputs/environments/add-independent-1.out
-   :language: spec
-
-
-Notice that ``spack add`` added the package to our active environment and it appears in the configuration file's spec list.
-
-.. note::
-
-   You'll need to run ``spack concretize`` and ``spack install`` to install added packages in your environment because ``spack add`` only adds it to the configuration and ``spack install`` only automatically concretizes the first time an environment is used.
-
-Now use ``spack remove`` to remove the spec from the configuration:
-
-.. literalinclude:: outputs/environments/remove-independent-1.out
-   :language: spec
+.. literalinclude:: outputs/environments/concretize-f-1.out
+   :language: console
 
-and we see that the spec *was* removed from the spec list of our environment.
+All the specs are now concrete with ``mpich`` as the MPI implementation, ready to be installed.
+Next you'd run ``spack install`` to rebuild the environment with the new MPI provider.
 
 .. note::
 
-   You can also edit the ``spack.yaml`` file directly instead of using the ``spack add`` and ``spack remove`` commands.
-
-^^^^^^^^^^^^^^^^^^^^^^^^
-Reviewing ``spack.lock``
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-Now let's turn our attention from the abstract to the concrete.
+   In general, when building an environment it is also possible to add and install specs one at a time, but Spack will then concretize each new spec *greedily* against the versions already locked in.
+   This can lead to a different (and sometimes less optimal) result than concretizing everything together.
 
-Our focus so far has been on the abstract environment configuration represented by the ``spack.yaml`` file.
-Once that file is concretized, Spack *generates* a corresponding ``spack.lock`` file representing the full concretized state of the environment.
+--------------------
+Sharing environments
+--------------------
 
-This file is intended to be a machine-readable representation of the information needed to *reproduce* the build of an environment.
-As such, it is written in ``json``, which is less readable than ``yaml``.
+The ``spack.yaml`` and ``spack.lock`` files we have been working with are not just a record of the environment: they are also the mechanism for sharing it.
+You can commit them to version control, hand them to a colleague, or drop them into a CI/CD pipeline.
+Anyone with a Spack installation can recreate the environment from them.
 
-Let's look at the top 30 lines of our current environment:
+To demonstrate, we'll play the role of the recipient of a shared environment.
+Let's build a fresh independent environment in a new ``code/`` directory, which stands in for a project a colleague has shared with us:
 
-.. literalinclude:: outputs/environments/lockfile-1.out
+.. literalinclude:: outputs/environments/independent-create-1.out
    :language: console
 
+Since the environment is independent, it must be activated by path, not by name.
+Edit the ``spack.yaml`` created in the directory to add ``trilinos`` and ``openmpi``:
 
-While it is still readable, it consists of over 1900 lines of information representing the actual configurations for each of the environment's packages.
+.. code-block:: yaml
 
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-Reproducing an environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^
+   # This is a Spack Environment file.
+   #
+   # It describes a set of packages to be installed, along with

+     specs:
+     - trilinos
+     - openmpi
+     view: true
+     concretizer:
+       unify: true
 
-Now that we've described the contents of the environment files we can discuss how they can be used to reproduce environments.
-You may want to do this yourself on a different machine, or use an environment built by someone else.
-The process is the same in either case.
+.. literalinclude:: outputs/environments/install-independent-1.out
+   :language: console
 
-You can recreate an environment by passing either of the environment files to ``spack env create``.
-The file you choose depends on whether you want to approximate the build using the abstract specs or an *exact* build based on the concrete specs.
+Passing either of these files to ``spack env create`` recreates the environment.
+The ``spack.yaml`` file preserves the abstract requirements but allows the concretizer to adapt to a new platform.
+The ``spack.lock`` file fixes every concretization decision and reproduces the build exactly.
 
-""""""""""""""""""""
+^^^^^^^^^^^^^^^^^^^^
 Using ``spack.yaml``
-""""""""""""""""""""
-
-An approximate build is created using the ``spack.yaml`` file.
-This approach is relevant when we want to build the same specs on a new platform, for example.
-It allows you to reproduce the environment by preserving the abstract requirements in the file.
-However, the software may actually build differently in part because the concretizer may choose different dependencies.
+^^^^^^^^^^^^^^^^^^^^
 
-Let's use ``spack env create`` to create an abstract environment from the file that we'll call ``abstract``:
+Recreating from ``spack.yaml`` preserves the root specs but leaves dependency resolution to the concretizer, which may produce different versions on a new platform or as packages are updated:
 
 .. literalinclude:: outputs/environments/create-from-file-1.out
    :language: console
 
-
-Here we see that Spack created a managed environment with the name we provided.
-
-And, since it is a newly created environment, it does not have any *installed* specs yet as we can see from calling ``spack find`` **after** activating the environment:
+The new environment has no installed packages yet, only the root specs from the file are registered:
 
 .. literalinclude:: outputs/environments/find-env-abstract-1.out
    :language: console
 
-Notice that we have the same root specs as were listed in the ``spack.yaml`` file.
-
-""""""""""""""""""""
+^^^^^^^^^^^^^^^^^^^^
 Using ``spack.lock``
-""""""""""""""""""""
-
-The ``spack.lock`` file is used for an exact reproduction of the original build.
-It can replicate the build because it contains the information for all the decisions made during concretization.
+^^^^^^^^^^^^^^^^^^^^
 
-Now let's create a concrete environment, called ``concrete``, from the file:
+Recreating from ``spack.lock`` reproduces the exact build, and thus requires the same machine architecture.
+All packages recorded in the lockfile are installed without a separate install step:
 
 .. literalinclude:: outputs/environments/create-from-file-2.out
    :language: console
 
-Here we see that Spack again created a managed environment with the provided name.
-
-Since we created the environment from our ``spack.lock`` file, not only do we get the same root specs, all of the packages are installed in the environment as we can see from calling ``spack find`` **after** activating the environment:
+Since the environment was created from ``spack.lock``, the root specs and all their dependencies are already installed:
 
 .. literalinclude:: outputs/environments/find-env-concrete-1.out
    :language: console
 
-.. note::
-
-   Use of ``spack.lock`` to reproduce a build (currently) requires you to be on the same type of machine.
