Installation instructions unclear for me

Description

I wanted to play around with this on Windows with my Oculus, but I can't understand all the installation instructions in https://github.com/leetvr/hotham/wiki/Getting-started.

• adb devices doesn't work, and don't understand which installation it would come from.

PS C:\Windows\system32> adb devices
adb : The term 'adb' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.

• We use [shaderc](https://github.com/google/shaderc) to compile our shaders at build time, so you'll need to make sure it's installed and available on your PATH.

How do I install shaderc? On their Github it isn't clear to me. I downloaded the binary from one of their links but it's a zip without an installer and I don't know what to do afterwards
