 ## Development Setup
 
-There are two ways to work on this project.
-For the first one you will need to install the Nix package manager[^1].
-Afterwards you can enter the development environment with `nix develop`.
+There is currently only one supported way to work with this repository. You
+will need a Linux system (WSL might work) onto wich you install the Nix package
+manager with Flakes enabled[^1] and direnv[^3]. Afterwards you can enter the
+development environment with `direnv allow`.
 
-For the other way you have to install poetry[^2] and then run `poetry shell` to
-enter the virtual environment.
+[^1]: https://nixos.org/download.html
+[^3]: https://direnv.net/
+
+After you've entered the development environment with either method you can
+start the development server with `dev run`. This will start a PostgreSQL
+database running and start the Django development server.
+
+_It will prompt you for your sudo password because it opens port 8000 in your
+firewall. This is because I sometimes develope from my iPad on my notebook and
+with this tweak I can access the dev server running on my notebook._
+
+You can then access the project in the browser under the FQDN of your
+computer. E.g. `http://mypc.domain.local:8000`.
+
+In case you want a fresh start or remove the project you can just remove the
+`.direnv` directory at the root of the project. All the data of the PostgreSQL
+database is stored there together with the symlinks to the Nix store.
+
+In case you want to tweak something these are the applications use do build the
+development environment:
+
+- Nix package manager
+- direnv
+- overmind[^4]
+
+The `dev` command is a simple BASH script called `dev.sh` at the root of the
+project.
+
+[^4]: https://github.com/DarthSim/overmind
+
+Run the `dev` command without an argument to see all options.
+
+> Why aren't you using Docker/containers for development.
+
+_I think containers have their uses but developing with them is in my opinion a
+pain in the ass. You just can't easily interact with the tools inside the
+container and you have to hack around to get your editor working with it.
+In addition they aren't fully reproducable. Nix solves all of these
+problems. Overmind then comes into play to orchestrate the few tasks that are
+required to get a development environment up an running._
+
+**Manual way**
+
+The manual way you have to install poetry[^2] and then run `poetry shell` to
+enter the virtual environment. You will then need a local PostgreSQL server or
+modify the settings so that you can use your prefered database.
 
 Please note that I will only use and test the first method.
 
-[^1]: https://nixos.org/download.html

 [^2]: https://python-poetry.org
 
-After you've entered the development environment with either method you can
-start the server. With the nix version you can start it with `dev run`. With
-poetry `./dev.sh run`. This will start a PostgreSQL database running inside a
-docker container and start the Django development server. You can then access
-it in the browser under the FQDN of your computer. E.g. `mypc.domain.local`.
-Run the `dev` command without an argument to see all options.
