+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+OpenSem builds on Laravel 9.
+
+Core application code lives in `app/`, while HTTP routes reside in
+`routes/` and Blade views in `resources/views/`. Reusable front-end
+assets (JS, SCSS, images) sit under `resources/` and are compiled into
+`public/` via Laravel Mix.
+
+Database blueprints are versioned in `database/migrations/` with seeds
+in `database/seeders/`.
+
+Tests are organised in `tests/Unit/` and `tests/Feature/`; keep large
+fixtures in `tests/Fixtures/` to avoid polluting source directories.
+
+## Build, Test, and Development Commands
+
+- `composer install` — install PHP dependencies defined in
+  `composer.json`.
+
+- `php artisan serve` — start a local HTTP server on port 8000.
+
+- `npm install && npm run dev` — install Node tooling and build UI
+  assets for development.
+
+- `npm run prod` — generate minified production assets in `public/`.
+
+- `php artisan migrate --seed` — apply database schema and load
+  default data for demo instances.
+
+- `./build.sh` — builds a `.tar.xz` that contains the production and
+  deployement ready source to be deployed.
+
+## Coding Style & Naming Conventions
+
+Follow PSR-12 with four-space indentation and `snake_case` database
+columns. Controllers, models, and Livewire components use StudlyCase
+class names; private methods remain `camelCase`. Run `composer run
+inspect` before opening a PR to execute `phpcs` and `phpstan`. For
+front-end changes, keep Blade sections in lowercase kebab IDs (for
+example, `@section('order-summary')`).
+
+## Testing Guidelines
+
+Use PHPUnit via `php artisan test`; target deterministic tests with
+clear Arrange/Act/Assert blocks. Feature tests should mirror top-level
+route names (e.g., `OrdersTest.php`). Unit tests belong in
+`tests/Unit/` and should stub external services. When adding
+migrations or service integrations, include coverage that exercises
+failure paths. For granular checks, `./vendor/bin/phpunit --filter
+FooTest` is acceptable, but always run the full suite before pushing.
+
+## Commit & Pull Request Guidelines
+
+Commits in this repo mix Conventional Commit prefixes (`new:`, `fix:`,
+`chg:`); `fix: prevent null totals`. Keep messages in the imperative
+mood and reference ticket IDs when available.
+
+Pull requests must describe scope, list schema or configuration
+changes, and note any manual follow-up (cron, storage links,
+queues).
+
+Attach screenshots or terminal logs when touching UI or console
+output, and ensure CI scripts (when available) pass.
+
+## Environment & Security Notes
+
+Copy `.env.example` to `.env` and run `php artisan key:generate`
+before local work. Never commit `.env`, `storage/`, or database dumps
+containing sensitive data. Use the Docker resources in `docker/` only
+for reproducible environments; keep secrets in your host overrides,
+not in version control.
