Hello, this is good idea, the Readme would need some reworking and clarifications. However, there are various cases (ganglion or not, linux, mac, windows, etc.), so maybe a dedicated "INSTALL" is even better.

I will mark that as an enhancement, you are welcome to work on it and make a pull request :)
