# Here are the steps:
# - Add `127.0.0.1 your-site.com` to /etc/hosts files with `sudo nano /etc/hosts`
# - Save this file as docker-compose.yml in the root of your project (along with composer.json)
# - Put your database to db.sql in the root of the project, if any
# - Execute `docker-compose up -d`
# - Wait for approximately 10-100 seconds
# - Navigate to `localhost`
