Visit the official Angular JS resources and set up your development environment as instructed.

You can find nearly everything you need here but you won't need to install Grunt or Bower for what we'll be doing in the labs (though you might need them for other modules you're taking).

I'd also recommend installing SourceTree and setting up either a bitbucket (my personal favourite!) or GitHub account (if you haven't got one already) to manage versioning control of all your labs.

Once you have SourceTree installed, you can easily set up a local git repository and sync it up remotely with you bitbucket account as described here. It's probably best to set it up from the command line first and then just 'drag-n-drop' your folder onto the SourceTree app - and you're done!
