Installing Git and Make
The first thing we need to install is Git, which we'll need in order to clone the jQuery source from the Github repository to our own computer so that we can work with the source files. We also need something called Make, but we only need to actually install this on Mac platforms because it gets installed automatically on Windows when Git is installed.
Tip
As the file we'll create will be for our own use only and we don't want to contribute to jQuery by pushing code back to the repository, we don't need to worry about having an account set up on Github.
Prepare for Lift Off
First we'll need to download the relevant installers for both Git and Make. Different applications are required depending on whether you are developing on Mac or Windows platforms.
Mac developers
Mac users can visit http://git-scm.com/download/mac for Git.
Next we can install Make. Mac developers can get this by installing XCode. This can be downloaded from https://developer.apple.com/xcode/.
