+By default **PHP-CLI 7.0** is running.

+
+The PHP-CLI is installed in the Workspace container. To change the PHP-CLI version you need to edit the `workspace/Dockerfile`.
+
+Right now you have to manually edit the `Dockerfile` or create a new one like it's done for the PHP-FPM. (consider contributing).

+#### Install PHP Extensions
+
+Before installing PHP extensions, you have to decide whether you need for the `FPM` or `CLI` because each lives on a different container, if you need it for both you have to edit both containers.
+
+The PHP-FPM extensions should be installed in `php-fpm/Dockerfile-XX`. *(replace XX with your default PHP version number)*.

+The PHP-CLI extensions should be installed in `workspace/Dockerfile`.
