+### Install
+
+If you are comfortable using Go and have >= 1.10 installed the usual `go get -u github.com/boyter/scc/` will install for you.
+
+If you are looking for binaries see [Releases](https://github.com/boyter/scc/releases) for Windows, GNU/Linux and macOS for both i386 and x86_64 bit machines.
+
+If you would like to assist with getting `scc` added into snap/apt/homebrew/chocolatey/etc... please submit a PR or at least raise an issue with instructions.
