 a tiny cli modlist editor for Factorio written in go
+
+## technologies used
+- written in [go](https://go.dev) using:
+  - [huh](https://github.com/charmbracelet/huh)
+  - [cli](https://github.com/urfave/cli)
+  - [log](https://github.com/charmbracelet/log)
+- written using [helix](https://helix-editor.com/)
+- tested on [void linux](https://voidlinux.org/)
+
+
+## factorio has a built in mod manager, so why?
+
+The in-game mod manager can't be used with a headless server, and editing JSON by hand just isn't my style.
