+As far as I'm concerned, Microfetch is significantly faster than every other
+fetch tool that I have tried. The only downsides of using Rust for the project
+(in exchange for speed and maintainability) is the slightly "bloated" dependency
+trees, and the increased build times. The latter is very easily mitigated with

+to use it to utilize the binary cache properly

+Microfetch is packaged in [nixpkgs](https://github.com/nixos/nixpkgs). It can be
+installed by adding `pkgs.microfetch` to your `environment.systemPackages`.
+Additionally, you can try out Microfetch in a Nix shell.

+nix shell nixpkgs#microfetch
+```
+
+Or run it directly with `nix run`
+
+```bash
+nix run nixpkgs#microfetch

 Non-Nix users will have to build Microfetch with `cargo`. It is not published
 anywhere but I imagine you can use `cargo install --git` to install it from
