+You can install =pumo-system-info= using the following command:
+#+begin_src sh
+cargo install --path .
+#+end_src
+
+** Flake Input
+You can add this repository in your flake inputs like so:
+#+begin_src nix
+inputs.pumo-system-info.url = "git+https://labs.phundrak.com/phundrak/pumo-system-info";
+#+end_src
+
+You can also make it follow your =nixpkgs= version with this:
+#+begin_src nix
+pumo-system-info = {
+  url = "git+https://labs.phundrak.com/phundrak/pumo-system-info";
+  inputs.nixpkgs.follows = "nixpkgs";
+};
+#+end_src
+
+You can now install =inputs.pumo-system-info.packages.${system}.default=
+as a package. =${system}= can be either =x86_64-linux= or =aarch64-linux=.

 * Performance
 Since this is a utility for bringing information to eww, this project
 needs to run fast. Fortunately, it does! Here are some benchmarks I
