+# Flake install
+Add this repo to your ```flake.nix```. The package is built using the unstable channel. You can overwrite this by setting ```inputs.nixpkgs.follows = "nixpkgs"``` (if your default is 26.05).
+
+**The binary is executed as ```torlnk```.**
+
+```nix
+inputs = {
+  ...
+  torlink.url = "github:baairon/torlink";
+  ...
+}
+```
+
+You can install the package in either home.nix or your configuration.nix depending on your preference.
+
+**User**
+```nix
+# home.nix
+{ pkgs, inputs, ... }: 
+
+{
+  home.packages = with pkgs; [
+    ...
+    inputs.torlink.packages.${pkgs.system}.default
+    ...
+  ];
+}
+```
+
+**System**
+```nix
+# configuration.nix
+{ pkgs, inputs, ... }: 
+
+{
+  environment.systemPackages = with pkgs; [
+    ...
+    inputs.torlink.packages.${pkgs.system}.default
