 Contributions that help improve performance in specific areas of Microfetch are
 welcome. Though, prepare to be bombarded with questions.
 
-## Hacking
-
-A Nix flake is provided. `nix develop` to get started. Direnv users may simply
-run `direnv allow` to get started.
-
-Non-nix users will need `cargo` and `gcc` installed on their system, see
