 ## Installation
 
-```shell
-pip install --index-url https://git.end-play.xyz/api/packages/profitroll/pypi/simple/ huepaper
+### Nix
+
+This project is a [Nix Flake](https://nixos.wiki/wiki/Flakes). If you
+have a recent version of the [Nix package manager](https://nixos.org/)
+installed and Flakes are enabled, run huepaper like this:
+
+``` example
+nix run github:Deleh/huepaper
+```
+
+Parameters can be passed by appending a double-dash:
+
+``` example
+nix run github:Deleh/huepaper -- -hue 0.5 --color lightblue
+```
+
+Global installation can be done by including this flake in your flaked
+NixOS configuration as always :)
+
+### Legacy
+
+Execute the following steps to run huepaper:
+
+``` example
+pip install -r requirements.txt
+./huepaper.py
+```
+
+```{=org}
+#+end_example
+```
+
+To install it in your Python environment run:
+
+``` example
+python setup.py install
 ```
