+# Services for flakes without flake-parts

+`process-compose-flake` provides the [`makeProcessCompose`](https://github.com/Platonic-Systems/process-compose-flake/blob/644a8a129f17d23df9e6cf58c9bb1097a0959ab1/nix/lib.nix#L48-L53) function, which accepts custom configurations and returns the [process-compose](https://github.com/F1bonacc1/process-compose) package.
