Support brew install

[at15]

Is it possible to support installing via brew using brew tap?

• go get will result in downloading dependencies and may mess up the workspace
• docker requires longer command to run it and may cause file permission issue (haven't tried, just guessing)

I won't make a PR even if I have time /w\
