Jake: You should try to use Git from the Terminal to download the entire project before resorting to the zip file method below. This way, you'll be able to run a quick Git command in Terminal to merge all my latest changes/additions to your copy of the project and even merge those changes with any you've on your version. To do so, try to run these commands:
cd ~/Documents
git clone https://github.com/projectew/BaerNetThis will download the project into a folder named BaerNet in your Documents folder. The files you're interested in are all under the src directory. The HTML is under src/html and the CSS is under src/css.
If you receive an error message, you can just visit https://github.com/projectew/BaerNet, click the green Code dropdown button, then the Download ZIP button at the bottom of the list. Extract that to your Downloads folder and it will contain the src diretory just like before.
