On linux you can still install with homebrew[1], but if you prefer you can install from source as well. Follow the installation instruction for installing Go, maybe your distro has a preferred way. Then you can clone the repo and either 1. install the binary with `go install` (make sure $GOPATH/bin in in your path variable) or 2. run with `go run main.go`.

On a side note, I am looking for help to add `clx` to linux package managers.
