 # BiomeJsBundle
 
+[![.github/workflows/ci.yaml](https://github.com/Kocal/BiomeJsBundle/actions/workflows/ci.yaml/badge.svg)](https://github.com/Kocal/BiomeJsBundle/actions/workflows/ci.yaml)
+
 This bundle makes it easy to use [Biome.js](https://biomejs.dev/) in your Symfony project,
 to lint and format your assets files without Node.js
 (ex: when using Symfony's [AssetMapper Component](https://symfony.com/doc/current/frontend/asset_mapper.html)).
 
 ## Installation
 
+Install the bundle with Composer:
+
 ```bash
-composer require kocal/biome-js-bundle
+composer require kocal/biome-js-bundle --dev
+```
+
+The bundle should have been automatically enabled in your Symfony application (`config/bundles.php`). 
+If that's not the case, you can enable it manually:
+
+```php
+// config/bundles.php
+return [
+    // ...
+    Kocal\BiomeJsBundle\KocalBiomeJsBundle::class => ['all' => true],
+];
+```
+
+## Configuration
+
+If you want to use a specific version of Biome.js, you can configure it in your `config/packages/kocal_biome_js.yaml`:
+
+```yaml
+kocal_biome_js:
+    version: v1.7.3
+```
+
+To [configure Biome.js it-self](https://biomejs.dev/reference/configuration), you must create a `biome.json` file at the root of your project.
+
+A recommended configuration for Symfony projects is to ignore files from `assets/vendor/`, `vendor/` and `public/bundles/`:
+```json
+{
+  "files": {
+    "ignore": [
+      "assets/vendor/*",
+      "vendor/*",
+      "public/bundles/*"
+    ]
+  }
+}
 ```
 
 ## Usage
 
-TODO
+The latest Biome.js CLI binary is automatically installed (if not already installed) when running one of the `biome:*` command.
+
+### `biome:check`
+
+Runs formatter, linter and import sorting to the requested files.
 
+```bash
+# Shows format and lint errors
+php bin/console biome:check .
+
+# Shows format and lint errors, and fix them if possible
+php bin/console biome:check . --apply
+```
+
+### `biome:ci`
+
+Command to use in CI environments. Runs formatter, linter and import sorting to the requested files.
+
+Files won't be modified, the command is a read-only operation.
+
+```bash
+# Shows format and lint errors
+php bin/console biome:ci .
