+
+## Running - Docker compose 
+
+I also wrote a rudimentary docker compose file which makes running much more simple. Just run
+
+`docker compose --env-file <desired mode> up`
+
+All relevant passthroughs and mounts are specified through the env-file, for which I configured 4 versions: production, debug (development in general), upload and check. These files will have to be adapted to your individual setup but can be reused more easily.
+
+> Note:
+>
+> The `debug` requires additional input. Once `docker compose up` is running, in a new session run `docker compose --env-file env/debug exec bash`. The live-mounted code is then under `/code`. Note that the `DEBUG=true` environment variable is still set. If you want to test things on production, run `export DEBUG=false`. 
 
 
 ## Building
 
-### Things to keep in mind
-The software (firefox, selenium, python) changes frequently. For non-breaking changes it is useful to regularly clean build the docker image! This is also crucial to update the code itself.

+In docker, simply run:
 
 `docker build -t auto_news --no-cache .`
+
 where the `Dockerfile` has to be in the working directory
 
+In docker compose, run the usual command, but append 
+
+`docker compose ... up --build`
