+## Local Development
+
+This project provides a convenient [dock](https://github.com/zero-to-prod/dock) script to simplify local development workflows within Docker containers.
+
+You can use this script to initialize the project, manage Composer dependencies, and run tests in a consistent PHP environment.
+
+### Prerequisites
+
+- Docker installed and running
+- A `.env` file (created automatically via the `dock init`z command, if it doesn’t already exist)
+
+### Initializing
+
+Use the following commands to set up the project:
+
+```shell
+sh dock init
+sh dock composer update
+```
+
+### Testing
+
+This command runs PHPUnit inside the Docker container, using the PHP version specified in your `.env` file.
+You can modify or extend this script to include additional tests or commands as needed.
+
+```shell
+sh dock test
+```
+
+Run the test suite with all versions of php:
+
+```shell
+sh test.sh
+```
+
+### Configuration
+
+Before starting development, verify that your `.env` file contains the correct settings.
+
+You can specify which PHP version to use for local development, debugging, and Composer operations by updating these variables in your `.env` file:
+
+```dotenv
+PHP_VERSION=7.1
+PHP_DEBUG=7.1
+PHP_COMPOSER=7.1
+```
+
+Make sure these values reflect the PHP versions you intend to use.
+If the `.env` file does not exist, run the `sh dock init` command to create one from the `.env.example` template.
