+Customize the environment variables using the [.env](.env) file.
+The file [.env.example](.env.example) provides an example with all the environment variables you can set.
+The variables not set in the `.env` file will fallback on a default value defined in the [docker-compose.yml](docker-compose.yml).
+
+> :warning: Be careful when deploying your solution since some environment variables are **security-related**.
