Cannot install with yarn

[Tomucha]

Hi there! I cannot install it no matter what:

$ yarn global add google-cloud-gui
00h00m00s 0/0: : ERROR: [Errno 2] No such file or directory: 'global'

$ yarn --version
0.32+git

... to be honest - I have no idea what I'm even doing. Never heard of yarn :-(

Ah, ok. I installed yarn with "apt-get install yarn" which is - God knows what. What I should do was install it through NPM
npm install -g yarn.

Maybe you want to mention it in README, just to make it more accessible for non-JS people.

Thanks!
