+* Nix flake for Xmobar
+This flake exposes a module to use with home-manager.
+Here is how to set it up:
+
+1. Add the nixmobar flake as an input to your NiOS flake:
+  #+BEGIN_SRC nix
+  inputs = {
+    nixmobar.url = "git+https://codeberg.org/xmobar/xmobar.git/?dir=nix";
+  };
+  #+END_SRC
+
+2. And then, where you import your `home.nix`, add `extraSpecialArgs` like this:
+  #+BEGIN_SRC nix
+  home-manager = {
+    extraSpecialArgs = {
+      inherit inputs nixmobar;
+    };
+    users.refaelsh = import ./home.nix;
+  };
+  #+END_SRC
+
+3. Final step, use the module in `home.nix`:
+  #+BEGIN_SRC nix
+  {
+    inputs,
+    ...
+  }:
+  {
+    home.stateversion = "24.05";
+  
+    imports = [
+      inputs.nixmobar.homemodules.mainmodule
+      # Other imports go here.
+    ];
+  
+  }
+  #+END_SRC
+
+* Example usage
+#+BEGIN_SRC haskell
