This relates to installing Sublime Text on Ubuntu 14.04 LTS.

For Sublime Text 2, run the following commands:

$ sudo add-apt-repository ppa:webupd8team/sublime-text-2
$ sudo apt-get update
$ sudo apt-get install sublime-text

For Sublime Text 3, run the following commands:

$ sudo add-apt-repository ppa:webupd8team/sublime-text-3
$ sudo apt-get update
$ sudo apt-get install sublime-text

Notice that it's just a case of changing sublime-text-2 to sublime-text-3.

Don't forget to Install Emmet (Zen Coding) and LESS highlighting too!
