-### Develop local package {#develop-local-package}
-
-As a Python developer you're likely aware of [development mode](http://setuptools.readthedocs.io/en/latest/setuptools.html#development-mode)
-(`python setup.py develop`); instead of installing the package this command
-creates a special link to the project code. That way, you can run updated code
-without having to reinstall after each and every change you make. Development
-mode is also available. Let's see how you can use it.
-
-In the previous Nix expression the source was fetched from a url. We can also
-refer to a local source instead using `src = ./path/to/source/tree;`
-
-If we create a `shell.nix` file which calls [`buildPythonPackage`](#buildpythonpackage-function), and if `src`
-is a local source, and if the local source has a `setup.py`, then development
-mode is activated.
-
-In the following example, we create a simple environment that has a Python 3.11
-version of our package in it, as well as its dependencies and other packages we
-like to have in the environment, all specified with `dependencies`.
-
-```nix
-with import <nixpkgs> {};
-with python311Packages;
-
-buildPythonPackage rec {
-  name = "mypackage";
-  src = ./path/to/package/source;
-  dependencies = [
-    pytest
-    numpy
-  ];
-  propagatedBuildInputs = [
-    pkgs.libsndfile
-  ];
-}
-```
-
-It is important to note that due to how development mode is implemented on Nix
-it is not possible to have multiple packages simultaneously in development mode.
