Installation

Requirements

First, make sure that you have Ruby (>= version 1.8) installed. You can do this by typing ruby --version in the command line.

• For Mac users, there's no need to do anything. Ruby comes with the OS by default.
• For Windows users, I don't know.
• For Ubuntu users, sudo apt-get install ruby.

Installation

Install Proton by typing:

$ gem install proton

If this process fails, you can instead try sudo gem install proton.
