+# PHPStan - PHP Static Analysis Tool
+
+## Project Overview
+
+PHPStan finds errors in PHP code without running it. It catches bugs before tests are written, moving PHP closer to compiled languages. This is the **distribution repository** — the compiled PHAR and supporting infrastructure. The actual source code lives at [phpstan/phpstan-src](https://github.com/phpstan/phpstan-src).
+
+- **Website:** https://phpstan.org/
+- **Documentation:** https://phpstan.org/user-guide/getting-started
+- **API Reference:** https://apiref.phpstan.org/
+
+## Repository Structure
+
+```
+├── phpstan                    # CLI entry point (shell script loading the PHAR)
+├── phpstan.phar               # Compiled PHAR archive (~26 MB)
+├── phpstan.phar.asc           # GPG signature for the PHAR
+├── bootstrap.php              # PHAR autoloader with PHP version polyfills
+├── composer.json              # Package definition (requires PHP ^7.4|^8.0)
+├── .phar-checksum             # MD5 + SHA1 checksums for reproducible builds
+├── conf/
+│   └── bleedingEdge.neon      # Bleeding edge configuration profile
+├── e2e/                       # End-to-end tests (~67 test scenarios)
+├── docker/                    # Dockerfiles for PHP 8.0–8.4
+├── identifier-extractor/      # Tool to extract error identifiers from rule source code
+├── playground-api/            # AWS Lambda API for the online playground (TypeScript)
+├── playground-runner/         # AWS Lambda runner for the playground (PHP/Bref)
+├── website/                   # phpstan.org static site (Eleventy + Vite + TailwindCSS)
+└── .github/workflows/         # CI/CD workflows
+```
+
+## Key Concepts
+
+### Distribution Model
+
+This repository distributes a pre-built PHAR archive. The source code is in [phpstan/phpstan-src](https://github.com/phpstan/phpstan-src), which is on PHP 8.1+ internally but the PHAR build is downgraded to support PHP 7.4+. The `phpstan` script loads the PHAR and delegates to the bundled binary.
+
+### PHP Version Support
+
+- **This distribution package:** PHP ^7.4|^8.0 (defined in composer.json)
+- **phpstan-src internally:** PHP 8.1+ (downgraded during PHAR build)
+- **Other extension repositories** (phpstan-strict-rules, phpstan-doctrine, phpstan-symfony, etc.): still support PHP 7.4+
+- **E2E tests run on:** PHP 7.4, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5 (Linux + Windows)
+
+### Bleeding Edge
+
+The `conf/bleedingEdge.neon` configuration enables experimental/strict checks before they become defaults. Users opt in by including this config.
+
+### Error Identifiers
+
+Every PHPStan error has a unique identifier (e.g., `argument.type`, `deadCode.unreachable`). The `identifier-extractor/` tool scans all PHPStan repositories to extract these identifiers, producing JSON used to generate documentation on the website.
+
+## Development
+
+
+### CI Workflows
+
+Key workflows in `.github/workflows/`:
+
+- **`tests.yml`** — Runs e2e tests on PHP 7.4–8.5, Linux + Windows. Triggered on changes to `e2e/**`, `phpstan`, `.phar-checksum`, `bootstrap.php`.
+- **`other-tests.yml`** — Additional integration tests (PHP-Parser, React Promise, etc.)
+- **`integration-tests.yml`** — Tests against major projects (Rector, Larastan, Carbon, etc.)
+- **`extension-tests.yml`** — Tests 1st-party PHPStan extensions (PHPUnit, Doctrine, Symfony, etc.)
+- **`release.yml`** — Creates GitHub release on tag push, uploads `phpstan.phar` and signature
+- **`docker-stable.yml`** / **`docker-nightly.yml`** — Builds multi-arch Docker images (arm64 + amd64) pushed to ghcr.io
+- **`extract-identifiers.yml`** — Extracts error identifiers from all PHPStan repos
+- **`website.yml`** — Builds and deploys phpstan.org
+- **`generate-error-docs.lock.yml`** — Generates error documentation using Claude
+
+### Current Branch
+
+The main development branch for this repository is `2.2.x`.
+
+## Website
+
+The website (phpstan.org) lives in `website/` and has its own `website/CLAUDE.md` with detailed instructions. Key points:
+
+- Built with Eleventy (11ty) + Vite + TailwindCSS
+- Two-stage build: `npm run build:11ty` then `npm run build:vite`
+- Deployed to AWS S3 + CloudFront
+- Error documentation in `website/errors/` is auto-generated (see `website/errors/CLAUDE.md`)
+
+## Playground
+
+The online playground at https://phpstan.org/try consists of two AWS Lambda services:
+
+- **playground-api/** — TypeScript API that orchestrates analysis across multiple PHP versions
+- **playground-runner/** — PHP Lambda (via Bref) that executes PHPStan against submitted code
+
+Both are deployed via the Serverless Framework to eu-west-1.
+
+## Docker
+
+Dockerfiles in `docker/` build images for PHP 8.0–8.4, based on `php:*-cli-alpine`. Images are published to `ghcr.io` as multi-architecture (arm64 + amd64). The images install PHPStan via Composer and use `phpstan` as the entrypoint.
+
+## Related Repositories
+
+- [phpstan/phpstan-src](https://github.com/phpstan/phpstan-src) — Main source code (PHP 8.1+, downgraded for PHAR)
+- [phpstan/phpstan-strict-rules](https://github.com/phpstan/phpstan-strict-rules) — Additional strict rules
+- [phpstan/phpstan-deprecation-rules](https://github.com/phpstan/phpstan-deprecation-rules) — Deprecation detection
+- [phpstan/phpstan-doctrine](https://github.com/phpstan/phpstan-doctrine) — Doctrine integration
+- [phpstan/phpstan-symfony](https://github.com/phpstan/phpstan-symfony) — Symfony integration
+- [phpstan/phpstan-phpunit](https://github.com/phpstan/phpstan-phpunit) — PHPUnit integration
+- [phpstan/phpstan-nette](https://github.com/phpstan/phpstan-nette) — Nette integration
+- [phpstan/phpstan-webmozart-assert](https://github.com/phpstan/phpstan-webmozart-assert) — Webmozart Assert integration
+- [phpstan/phpdoc-parser](https://github.com/phpstan/phpdoc-parser) — PHPDoc parser library
+
+Extension repositories support PHP 7.4+ and some support multiple versions of the libraries they analyse.
+
+## Making Changes
+
+- **Source code changes** belong in [phpstan/phpstan-src](https://github.com/phpstan/phpstan-src), not here
+- **E2E tests** can be added or modified in `e2e/`
+- **Website content** is in `website/src/` (see `website/CLAUDE.md`)
+- **Error documentation** is in `website/errors/` (see `website/errors/CLAUDE.md`)
+- Configuration uses NEON format (Nette Object Notation), similar to YAML
