Missing a word in Linux install documentation

Hello,

You forgot the keyword "install" in Linux install documentation :

Make sure Python 2.x is installed. sudo apt-get python for debian users. Other distros will vary. Install pyusb from your software center and pip.

Should be :

Make sure Python 2.x is installed. sudo apt-get install python for debian users. Other distros will vary. Install pyusb from your software center and pip.

Thanks a lot for you awesome work !
