OK, lets step by step this. I know NetBeans better than Eclipse so that's what I'll talk about. Easiest way to do it (at this stage, harder later though!)
1) Download the files from Github.
2) Open Netbeans
3)File->New Project->Java Project With Existing Sources
4) Next
5) Browse to the folder you downloaded
6) Next
7) Add ALL of the folders to the Source Package Folders list
8) Next
9) Finish
Possibly:
10) Add new libraries as needed (let me know if this happens)
