+## Quick start
 
-Clone this repository:
+First, you must clone the [openproject-deploy](https://github.com/opf/openproject-deploy/tree/stable/14/compose) repository:
 
 ```shell
 git clone https://github.com/opf/openproject-deploy --depth=1 --branch=stable/14 openproject

+After a while, OpenProject should be up and running on `http://localhost:8080`. The default username and password is login: `admin`, and password: `admin`. 
+The `OPENPROJECT_HTTPS=false` environment variable explicitly disables HTTPS mode for the first startup. Without this, OpenProject assumes it's running behind HTTPS in production by default.
+We do strongly recommend you use OpenProject behind a TLS terminated proxy for production purposes and remove this flag before actually starting to use it.
+
+### Customization
+
+The `docker-compose.yml` file present in the repository can be adjusted to your convenience. But note that with each pull, it will be overwritten. 
+Best practice is to use the file `docker-compose.override.yml` for that case. 
+For instance you could mount specific configuration files, override environment variables, or switch off services you don't need.
+
+Please refer to the official [Docker Compose documentation](https://docs.docker.com/compose/extends/) for more details.
