+# Private Packagist API Client
+
+PHP API client for Private Packagist.
+
+## Commands
+
+- `composer test` — Run tests
+- `composer cs-fix` — Fix code style (src + tests)
+- `composer analyze` — Run PHPStan static analysis
+
+## Architecture
+
+- `src/Api/AbstractApi.php` — Base class for all API endpoints. Provides `get()` for single resources and `getCollection()` for list endpoints with auto-pagination.
+- `src/Api/*.php` — API endpoint classes (Packages, Teams, Customers, etc.)
+- `src/Api/*/` — Nested API endpoints (e.g. `Customers/VendorBundles`, `Packages/Artifacts`)
+- `src/Client.php` — Entry point, provides access to all API classes
+
+## Notes
+
+- Supports PHP 7.2+ — avoid modern syntax not available in 7.2
+
+## Conventions
+
+- List endpoints use `getCollection()` (handles pagination and default limit)
+- Single-resource endpoints use `get()`
