+# Contributing to Phred
+
+Thank you for your interest in Phred! We welcome contributions of all kinds.
+
+## RFC Process
+
+For major changes, please open an issue first to discuss what you would like to change.
+
+1. Create a "Request for Comments" (RFC) issue.
+2. Wait for feedback from the core maintainers.
+3. Once approved, submit a Pull Request.
+
+## Pull Request Process
+
+1. Fork the repository and create your branch from `main`.
+2. If you've added code that should be tested, add tests.
+3. Ensure the test suite passes (`composer test`).
+4. Ensure static analysis passes (`composer analyze`).
+5. Ensure code style matches PSR-12 (`composer fix`).
+6. Update the documentation if necessary.
+
+## Code of Conduct
+
+Please be respectful and professional in all interactions.

+*   `API_FORMAT`: The default API format (`rest` or `jsonapi`).
+*   `MODULE_NAMESPACE`: The base namespace for your modules (default: `Modules`).
+*   `APP_DEBUG`: Enable debug mode (`true` or `false`).
+*   `COMPRESSION_ENABLED`: Enable response compression (Gzip/Brotli).

 The `phred` binary provides several utility and scaffolding commands.
@@ -81,8 +90,54 @@ The `phred` binary provides several utility and scaffolding commands.
 ### Testing & Utilities
 * `php phred test` — Run tests for the entire project.
 * `php phred test:<module>` — Run tests for a specific module.
+* `php phred module:list` — List all discovered and registered modules.
+* `php phred module:sync-ns` — Sync `composer.json` PSR-4 with `MODULE_NAMESPACE`.
 * `php phred list` — List all available commands.
 
+## Routing
+
+Routes are defined in `routes/web.php`, `routes/api.php`, or within your module's `Routes/` directory. Phred uses `nikic/fast-route` for high-performance routing.
+
+### Basic Routes
+
+You can define routes using the `$router` instance:
+
+```php
+// routes/web.php
+$router->get('/welcome', WelcomeController::class);
+$router->post('/submit', SubmitFormController::class);
+```
+
+### Route Groups
+
+Groups allow you to share prefixes and middleware:
+
+```php
+$router->group(['prefix' => '/api', 'middleware' => 'api'], function ($router) {
+    $router->get('/users', ListUsersController::class);
+    $router->get('/users/{id}', ShowUserController::class);
+});
+```
+
+### Module Auto-Mounting
+
+Phred automatically mounts module routes based on folder name:
+- `modules/Shop/Routes/web.php` → mounted at `/shop`
+- `modules/Shop/Routes/api.php` → mounted at `/api/shop` (with `api` middleware)
+
+### Route Listing & Caching
+
+View all registered routes:
+```bash
+php phred route:list
+```
+
+In production, cache your routes for maximum performance:
+```bash
+php phred route:cache
+php phred route:clear # To clear cache
+```
+
