From the site you can preview and download the fonts. The only problem with that is you have to download them one by one. What if you want access to all of them at once?
Joe Maller to the rescue! The other day I ran across this blog post that detailed how Joe Maller had individually downloaded all of the current fonts and put them in a single folder for download. You’ll need an application like 7zip (which is free and the one I use) to decompress the files. Once they’re decompressed, you can easily install the fonts on your computer.
Are these really free?

When you download the fonts you have the option to pay the developers. Paying someone for their work isn’t a bad idea and probably motivates them to create some more fonts and make those available, as well.
