+## Build PHP 7.0 Docker image
+Use the build script in order to build the custom PHP 7.0 Docker image
+`andrerademacher/codewars-php70`.
+
+```bash
+container/build.sh
+```
+
+## Run command in container
+The `container.sh` script makes running commands in the Docker container easy!
+To open a shell, just add the "sh" command:
+```bash
+container.sh sh
+```
+
+The current PHP version can be shown like this:
+```bash
+container.sh php --version
+```
+
+The Composer binary is already present in the latest 2.2 LTS version supporting PHP 7.0 .
+To run any composer command, like `composer install`, just type:
+```bash
+container.sh composer install
+```
+
+After installing the dev dependencies, the PHPUnit test suite can be run
+inside the container by calling the phpunit binary in the vendor directory:
+```bash
+container.sh vendor/bin/phpunit
+```
+
+For convenience, this can be done also by using the composer script:
+```bash
+container.sh composer phpunit
+```
