 # GraphQLite bundle
 
 Symfony bundle for the `thecodingmachine/graphqlite` package.
+It discovers your annotated controllers and types, builds the schema, exposes the `/graphql` endpoint through a PSR-7
+bridge (with optional upload handling), and keeps the Symfony request available as the GraphQL context.
 
-Bundle docs: https://graphqlite.thecodingmachine.io/docs/symfony-bundle
+Part of the bundle docs: https://graphqlite.thecodingmachine.io/docs/symfony-bundle
 
 See [thecodingmachine/graphqlite](https://github.com/thecodingmachine/graphqlite).
+
+## Requirements
+
+- PHP 8.1+
+- Supports:
+  - Symfony 6.4/7.0/8.0
+  - GraphQLite ^8
+
+## Installation
+
+```bash
+composer require thecodingmachine/graphqlite-bundle
+```
+
+Ensure the bundle is enabled (Symfony Flex does this automatically via `config/bundles.php` after `composer require`).
+
+### Configure routes
+
+Import the bundle routes to expose `/graphql`:
+
+```yaml
+# config/routes/graphqlite.yaml
+graphqlite_bundle:
+  resource: '@GraphQLiteBundle/Resources/config/routes.php'
+```
+
+### Configure namespaces
+
+Tell GraphQLite where to look for controllers and types:
+
+```yaml
+# config/packages/graphqlite.yaml
+graphqlite:
+  namespace:
+    controllers: App\\GraphQL\\Controller
+    types:
+      - App\\GraphQL\\Type
+      - App\\Entity
+```
+
+## Quickstart
+
+Create a controller with GraphQLite attributes:
+
+```php
+<?php
+// src/GraphQL/Controller/HelloController.php
+namespace App\GraphQL\Controller;
+
+use TheCodingMachine\GraphQLite\Annotations\Query;
+
+final class HelloController
+{
+    #[Query]
+    public function hello(string $name = 'world'): string
+    {
+        return sprintf('Hello %s', $name);
+    }
+}
+```
+
+## Features
+
+- Auto-discovers controllers and types from configured namespaces and registers GraphQLite services, query providers,
+  type mappers, and middleware through Symfony autoconfiguration
+- Ships a `/graphql` route that converts Symfony requests to PSR-7 and keeps the Symfony request in the GraphQL context
+- Passes the Symfony request as context to allow using them in queries/mutations
+- Supports multipart uploads when `graphql-upload` is installed
+- Integrates with Symfony Security for `#[Logged]`/`#[Right]` checks
+- Expose `login`/`logout` mutations plus a `me` query (opt-out)
+- Symfony Validator-based user input validation
+- Lets you cap introspection, query depth, and query complexity via configuration
+- Uses Symfony cache (APCu or PHP files) for schema caching
+- Includes a `graphqlite:dump-schema` console command to export GraphQL SDL
+
+## GraphiQL (playground)
+
+The bundle wires Overblog’s GraphiQL bundle if it is installed. See https://github.com/overblog/GraphiQLBundle for
+enabling the UI alongside the `/graphql` endpoint.
+
+## Development
+
+- Tests: `vendor/bin/phpunit`
+- Static analysis: `composer phpstan`
