+# Installation
+
+Installing `mkosi` is easy, as it has no runtime Python dependencies (you will
+need all the tools to format filesystems and bootstrap the distribution
+appropriate for your image, though).
+
+If you just want the current master branch you can run
+```shell
+python3 -m pip install --user git+https://github.com/systemd/mkosi.git
+```
+
+If you want to hack on mkosi do
+```shell
+# clone either this repository or your fork of it
+git clone https://github.com/systemd/mkosi/
+cd mkosi
+python3 -m pip install --user --editable .
+```
+This will install mkosi in editable mode to `~/.local/bin/mkosi`, allowing you
+to use your own changes right away.
+
+For development you optionally also need [mypy](https://github.com/python/mypy)
+and [pytest](https://github.com/pytest-dev/pytest). We check tests and typing in
+CI (see `.github/workflows`), but you can run the tests locally as well.
