 ## Modules
 
 There will be a link to the documentation for each module. This repository is still work in progress
+
+## Development
+
+I am using [nh](https://github.com/nix-community/nh) for my nixos configuration and this is alos how I develop/test the modules. Below is the command.
+This works for me, because I have configured nh to know where my primary flake is located.
+
+```bash
+nh home switch -- --override-input dotfiles-modules path:$(pwd)
+```
+
+If you forked this repository and want to make some changes something along the lines of the second command could suit your needs.
+
+```
+home-manager switch --flake <path-to-your-local-flake> --override-input dotfiles-modules path:$(pwd)
+```
+
+**Note:** In the future I might add nixos modules too, in which case I will update the commands becuase the `home-manager` / `nh` command will only update the home config.
