 # Installing
-Swaymux is packaged as a nix flake. To install it, add the flake input, e.g. using the following snippet:
+## Requirements
+This system expects the `$SWAY_SOCK` environment variable to be set and the associated socket to be bindable. If that isn't the case, this program will fail to launch.
+Further, on Nix and NixOS the runtime dependencies should already be packaged. For any other system i currently do not have a good way to test, but a valid QT QPA platform plugin should be all that is needed runtime.
+
+## Nix and NixOS
+Swaymux is packaged as a nix flake. It can be tested using `nix run git+https://git.grimmauld.de/Grimmauld/swaymux`, this will build and launch swaymux in a temporary environment that will be removed at next garbage collect in store.
+
+To install swaymux permanently, add the flake input, e.g. using the following snippet:
 ```nix
 swaymux = {
   url = "git+https://git.grimmauld.de/Grimmauld/swaymux";

-Keep in mind you'll need to make the system constant available, e.g. by setting `specialArgs = { inherit inputs system; };` as part of your nixosSystem definition in your systems flake.
+If you want to directly copy this, keep in mind you'll need to make the system and inputs constants available, e.g. by setting `specialArgs = { inherit inputs system; };` as part of your nixosSystem definition in your systems flake.
 
+## Other systems
+This project uses cmake and requires the [nlohman json library](https://github.com/nlohmann/json) as well as QT6.
+Last time I tested, both GCC and clang compilers worked. Therefore, the classic installation process with cmake, make and make install should just work, though I currently do not have a good way to test. 
+
+
+## Integrating with sway
 Once the package is available, it can be made available in sway by keybinding. Setting swaymux to be floating is recommended.
 ```sway
 for_window [app_id="swaymux"] floating enable
 bindsym $mod+c exec swaymux
 ```
 Available key bindings can be viewed in-App.
+
+# Developing
+On Nix, the flake makes `nix develop` available, which provides a development environment with all the required dependencies. It does however not provide an IDE by itself.
+On any other system, or if you don't like `nix develop`, the standard way of developing cmake based c++ projects should work. Just make sure both compile and runtime dependencies are available.
