 # WIP SMC fonts flake
 
-This is a WIP Flake that can install SMCs fonts. 
+This is a WIP Flake that can install SMCs fonts. Currently, the following are supported.
+
+1. Anjali Old Lipi
+2. Chilanka
+3. Manjari
+4. Gayathri
+
+*NOTE* I am not that familiar with nix flakes yet. This repo will see a lot more activity and perhaps significant change in structure in the near future.
+
+## Using with a flakes+home-manager based nixOS setup
+
+In the inputs section
+
+```
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    
+	# Other flakes/modules/inputs
+	
+    smcFonts.url = "gitlab:smc/smc-fonts-flake/trunk";
+    smcFonts.inputs.nixpkgs.follows = "nixpkgs";
+  };
+```
+
+In the outputs section of the flake:
+
+```
+# Note the smcFonts being passed as an argument
+ outputs = { self, nixpkgs, smcFonts, <other inputs>  }@inputs:
+    let platforms = [ "x86_64-linux" ];
+    in {
+
+      nixosConfigurations = {
+        hex = nixpkgs.lib.nixosSystem {
+          system = "x86_64-linux";
+          specialArgs = { inherit inputs; }; # <-- The inputs are being passed down to the modules
+          modules = [
+            (import ./hosts/default.nix)
+          ];
+        };
+
+    };
+}
+```
+
+Lastly, in `default.nix`
+
+```
+{ config, lib, pkgs, modulesPath, inputs, ... }: # <-- "inputs" is an argument
+let
+  smc-fonts = inputs.smcFonts.packages."${pkgs.system}".default; # <-- by default, it will install all fonts
+in
+{
+ 
+  home-manager.users.<username> = { pkgs, ...}: {
+  
+    home.packages = with pkgs; [
+    	# list of home manager packages 
+		smc-fonts # what we defined above.
+```
