This release has binaries. Download an archive for your platform, extract, and run. For now, they are still command-line applications that you need to run from the terminal, but at least there should be no problems with python and pip installation.
There are binaries for windows, mac os, linux and arm linux (aarch64, like raspberry pi, pine64 etc).
