+TestApplication
+===============
+
+Developer tool that provides a ready-to-use Sylius-based application for testing and running Sylius plugins.
+
+> ⚠️ While TestApplication is still evolving, it is already being used internally and in official plugins.
+   We encourage you to adopt it in your plugins, provide feedback, and contribute to improve the developer experience 
+   for the entire Sylius ecosystem.
+
+## Purpose
+
+Previously, each plugin had to maintain its own copy of a test application, leading to duplicated configuration, 
+maintenance overhead, and version incompatibilities.
+
+This package solves that problem by:
+
+- Extracting a reusable, standalone test application
+- Providing an official, centrally maintained solution by the Sylius team
+- Simplifying the setup and execution of tests within plugins
+- Creating versioned variants aligned with specific Sylius versions (e.g. `1.14`, `2.0`, etc.)
+
+## Installation and configuration in a Plugin
+
+1. Require the TestApplication as a development dependency:
+
+    ```bash
+    composer require sylius/test-application:2.0.x-dev --dev
+    ```
+
+1. Set environment variables in `tests/TestApplication/.env`:
+
+    ```dotenv
+    DATABASE_URL=mysql://root@127.0.0.1/test_application_%kernel.environment%
+    BUNDLES_TO_ENABLE="Acme\Plugin\AcmePlugin"
+    CONFIGS_TO_IMPORT="@AcmePlugin/tests/TestApplication/config/config.yaml"
+    ROUTES_TO_IMPORT="@AcmePlugin/config/routes.yaml"
+    ```
+
+    > 💡 The values provided above are examples and should be adjusted for your plugin.
+
+
+1. If needed, place plugin-specific configuration files in the `tests/TestApplication/config` directory
+   (e.g. `services.yaml`, `routes.yaml`) and load them by env variables.
+
+1. If your plugin requires additional JavaScript dependencies, add them to `tests/TestApplication/package.json`:
+
+    ```json
+    {
+        "dependencies": {
+            "trix": "^2.0.0"
+        }
+    }
+    ```
+
+   This file will be merged with the main TestApplication `package.json`.
+
+1. If your plugin requires entity extensions, add them in `tests/TestApplication/src/Entity` and ensure:
+
+    - Doctrine mappings are configured:
+
+        ```
+        doctrine:
+            orm:
+                entity_managers:
+                    default:
+                        mappings:
+                            TestApplication:
+                                is_bundle: false
+                                type: attribute
+                                dir: '%kernel.project_dir%/../../../tests/TestApplication/src/Entity'
+                                prefix: Tests\Acme\Plugin\TestApplication
+        ```
+      
+    - The namespace is registered properly in the autoloader, in `composer.json` file
+
+        ```json
+        {
+            "autoload-dev": {
+                "psr-4": {
+                    "Tests\\Acme\\Plugin\\TestApplication\\": "tests/TestApplication/src/"
+                }
+            }
+        }
+
+1. Build the TestApplication in a Plugin:
+
+    ```bash
+    vendor/bin/console doctrine:database:create
+    vendor/bin/console doctrine:migration:migrate -n
+    vendor/bin/console sylius:fixtures:load -n
+    
+    (cd vendor/sylius/test-application && yarn install)
+    (cd vendor/sylius/test-application && yarn build)
+    vendor/bin/console assets:install
+    ```
+
+1. Run your server locally:
+
+    ```bash
+    symfony serve --dir=vendor/sylius/test-application/public
+    ```
+
+## Example usage
