The installation instructions mention Render but doesn't say what it's needed for, or if it's needed. Is only the Docker needed? Can you provide more details on the installation page?
The other installation methods are docker (https://automatisch.io/docs/guide/installation#docker) and docker compose. (https://automatisch.io/docs/guide/installation#docker-compos...) You can choose one of them. I think most of our users are using Docker setup atm.
Please let me know if you have any other questions.
