 If all the conditions are met, you can proceed with the following steps:
 
-1. Install PHP/Composer dependencies with **`docker-compose run app composer install`** (first time can take a while because the image has to be built).
-2. **Copy `.env.example` to `.env`** and change `APP_KEY` to a random 32 char string.
