-Normally, you'd add `@fluentui/react` to your project using `yarn add <package>`. However, since we want to test our local changes to the `fluentui` package, this will not be sufficient. This is where `yarn link` saves the day. `yarn link` creates a symlink to your local package inside the `node_modules` directory, however, at the same time, it doesn't add the dependency to the `package.json` file. Having said that, you can still import the linked package as you'd normally do when adding a package from the npm registry. So no difference there. The trick is with the actual linking. We discuss this next.
+Normally, you'd add `@fluentui/react` to your project using `yarn add <package>`. However, since we want to test our local changes to the `fluentui` package, this will not be sufficient. This is where `yarn link` saves the day.
 
 ## The solution
 
-We want to link `@fluentui/react` as a dependency of the `app` package. To do this, we first of all need to add our local copy of `@fluentui/react` into `yarn`'s link registry. This can be done by navigating to the `fluentui` project and then into the appropriate package source directory, in this case, `react`, and invoking `yarn link`:
+Yarn 4 supports path-based linking directly, without a global link registry. From the `app` directory, point Yarn at the local package source:
 
-```
-$ cd fluentui/packages/react
-$ yarn link
-yarn link v1.22.10
-success Registered "@fluentui/react".
-info You can now run `yarn link "@fluentui/react"` in the projects where you want to use this package and it will be used instead.
-✨  Done in 0.04s.
-```
-
-OK, so we're halfway there. Now, from within the `app`'s root directory, we execute the hint given to us by `yarn link`, that is:
-
-```
+```bash
 $ cd app
-$ yarn link @fluentui/react
-yarn link v1.22.10
-success Using linked package for "@fluentui/react".
-✨  Done in 0.04s.
+$ yarn link ../fluentui/packages/react
 ```
 
-After this is done, if you navigate into your `app`'s `node_modules` dir, you'll see that `@fluentui/react` is a symlink:
+This records the local path for `@fluentui/react` in `app/package.json` under `resolutions` using Yarn's
+[`portal:` protocol](https://yarnpkg.com/protocol/portal) and installs the link. The package is now resolved from your
+local `fluentui/packages/react` directory — no separate registration step needed in the library.
 
-```
-$ cd app/node_modules/@fluentui
-$ ls -la react
-lrwxr-xr-x  1 username  group  45 Jan 11 13:03 node_modules/@fluentui/react -> ../../../../.config/yarn/link/@fluentui/react
-```
+> **Warning:** If you encounter a [React "Rules of Hooks" error](https://reactjs.org/warnings/invalid-hook-call-warning.html), both projects are loading separate copies of `react`. Yarn 4 path linking preserves the consuming app's peer dependency resolution, so the linked package should resolve `react` through the app's own `node_modules`. If the error still occurs, verify that the app and the linked package declare compatible `react` peer versions. Do not add self-referential `link:./node_modules/react` resolutions — they are circular and unreliable.
 
-This symlink points to `yarn`'s local link-registry, which in turn dereferences to the `fluentui/packages/react` directory:
-
-```
-$ ls -la ~/.config/yarn/link/@fluentui/react
-lrwxr-xr-x  1 username  group  39 Jan 11 11:56 ~/.config/yarn/link/@fluentui/react -> ../../../../common_root/fluentui/packages/react
-```
-
-In effect, you can think of it as:
+With this done, you should be able to successfully run the app:
 
-```
-common_root
- \
-  | -- fluentui
-  |     \
-  |      | -- packages/react <---------|
-  |                                    |
-  | -- app                             |
-        \                              |
-         | -- node_modules/@fluentui/react
+```bash
+$ yarn start
 ```
 
-If you try running your app however, you will get greeted by a nasty looking [React error scolding you for violating the "Rules of Hooks"](https://reactjs.org/warnings/invalid-hook-call-warning.html). The good news is, we've not violated anything. The bad news is, the app will refuse to launch. It turns out, in addition to violating the "Rules of Hooks", this problem also surfaces when the two projects you want to link locally via symlink both add `react` and `react-dom` as dependencies. In such case, as prescribed by React, it is necessary to manually link in the same version of `react` and `react-dom` between the linked packages using `npm link <path>`, and is best done in the lib's `node_modules`:
-
-```
-$ cd fluentui
-$ rm -rf fluentui/node_modules/react # please, be extremely careful when invoking rm with -rf flags!
-$ rm -rf fluentui/node_modules/react-dom
-$ npm link ../app/node_modules/react
-$ npm link ../app/node_modules/react-dom
-```
+## Unlinking
 
-With this done, you should be able to successfully run the app:
+To restore the original published version, remove the entry `yarn link` added for `@fluentui/react` from the `resolutions` field in `app/package.json`, then reinstall:
 
-```
-$ yarn start
+```bash
+$ cd app
+$ yarn install
 ```
 
 ## Development workflow
 
 Now, whenever you make tweaks to the `fluentui` lib, you simply need to rebuild it via:
 
-```
+```bash
 $ cd fluentui
 $ yarn nx run react:build
