 This probably won't need to be changed, it's only there to set basic environment
 variables for the docker compose file.

-### Building the container
-
-The container provided is a thin wrapper around akkoma's dependencies, 
-it does not contain the code itself. This is to allow for easy updates
-and debugging if required.
-
-```bash
-./docker-resources/build.sh
-```
-
-This will generate a container called `akkoma` which we can use
-in our compose environment.

 ### Generating your instance

 ```bash
 mkdir pgdata
-./docker-resources/manage.sh mix deps.get
-./docker-resources/manage.sh mix compile
-./docker-resources/manage.sh mix pleroma.instance gen
+./docker-resources/generate-instance.sh
 ```

-This will ask you a few questions - the defaults are fine for most things,
-the database hostname is `db`, the database password is `akkoma`
-(not auto generated), and you will want to set the ip to `0.0.0.0`.

-### Setting up the database 
-

-```bash
-docker compose run --rm --user akkoma -d db 
-# Note down the name it gives here, it will be something like akkoma_db_run
-docker compose run --rm akkoma psql -h db -U akkoma -f config/setup_db.psql
-docker stop akkoma_db_run # Replace with the name you noted down
