 ### Getting started
 
-#### Python
-
 Have Python >= 3.12 installed. I recommend [pyenv] (which in turn is easily
 installed by [homebrew]).
 
-#### PostgreSQL
-
-Set up PostgreSQL, a role and a schema.
-
-I have it on localhost, using the project name for role and schema name, and
-password. Using a VM, docker or even a remote instance is possible: See
-`.env.test` for providing connection information.

 virtualenv.) Run `python -m pip install -U pip` to upgrade pip. Then `python -m

 ## Dependency management
 
 This project uses [pip-compile-multi] for hard-pinning dependencies versions.
 Please see its documentation for usage instructions. In short,
-`requirements/prod.in` contains the list of direct requirements with occasional
-version constraints (like `Django<2`) and `requirements/prod.txt` is
+`requirements/base.in` contains the list of direct requirements with occasional

 automatically generated from it by adding recursive tree of dependencies with
 fixed versions. The same goes for `test` and `dev`.

 A useful command is `pip-sync requirements/dev.txt`, it uninstalls packages
 from your virtualenv that aren't explicitly specified as dependencies.
 
-## More on tools that are used
-
-These are not strictly necessary but very convenient.
-
-### Direnv (automatic venv)
-
-When direnv is [integrated into the shell](https://direnv.net/docs/hook.html)
-entering the project directory for the first time will cause direnv to create a
-hidden directory for the virtual environment.
-
-It will also activate that existing virtualenv automatically upon entering the
-project directory.
-
-#### Subshells or Shells started from Editors
-
-If your editor spawns a shell window or new terminal, it might be necessary to
-`direnv reload` before running any commands. This will make sure direnv has
-things set up. neovim's terminal requires this.
-
-### just
-
-[just] is used as a task runner. Think "makefile" but less confusing. (make is
-a build tool and task runner and much more, just intends to be a task runner.)
-
-If you don't want to install just, you can still look at its `justfile` to see
-how test runners, linters, dev servers and such are to be executed.
