+This repository has the purpose to develop a webapplication that can be used by
 JDAV to send newsletters, manage user lists and keep material lists up to date.
 As this repository is also meant to be a base for exchange during development, feel free
 to contribute ideas in form of edits to this README, issues, landmarks, projects, wiki entries, ...
 
-# Setup
+# Docker
 
-## Development server
+In the `docker` subfolder, there are `docker-compose.yaml`s for development and production use. For the development
+version, no further setup is needed.
 
-1. Install `virtualenv` (with pip3)
+# Production
-2. Create a new virtualenv with `virtualenv --no-site-packages -p python3.9`
-3. Activate the environment with `source venv/bin/activate`
-4. Install requirements with `pip3 install -r requirements.txt`
-5. Setup a MySQL database called `jdav_db` and create a user that can access this database.
-6. Create a `my.cnf` at `jdav_web/my.cnf` with username and password for the mysql database.
-7. Change working directory to `jdav_web` and execute `python3 manage.py runserver`
 
-## Deployed version
+In production, the docker setup needs an external database. The exact access credentials are configured in the respective
-
+docker.env files.
-- Mostly the same as the development version
-- Check the README on the server for further information.
