What is it?

According to its webpage:

A full-featured package manager that helps discovering, installing, updating and removing packages for Sublime Text 2. It features an automatic upgrader and supports GitHub, BitBucket and a full channel/repository system.

What's it mean? It's a Sublime Text package that makes it super-easy & convenient to install & manage all your other Sublime Text packages. Because of the ease of use it offers, Package Control really should be the first Sublime Text package you install.

Install the Package Control package

Follow these steps:

1. Go to http://wbond.net/sublime_packages/package_control/installation & copy the long command there.
2. Open the Sublime Text 2 console by pressing Ctrl+`.
3. Paste the command you copied into the Sublime Text console.
4. Press Enter.
5. After Package Control installs, restart Sublime Text.

Usage

Follow these steps:

1. Press Command-Shift-P (Mac OS X) or Ctrl-Shift-P (Windows) to open the Command Palette.
2. Start typing Package Control until you see the appropriate commands.

Some of the possible commands are:

  Temporarily turn off a package (if you think it's causing problems, for instance)
• Discover Packages
  List all available packages in your web browser
