How to download Snap Web client?

How do I get the Snap web client on to my Apache Web Server?

Click on the Snap! logo in the top left corner, and one of the menu choices is "download source." That will take you to the github repo, which you can download.

Thanks for the help, I figured that but... how do I install 'Snippets' to my Raspberry Pi?

Oh, you want to duplicate the community site with projects posted and all that? If you just want a Snap! server, you just need the one repo where your Apache can find it.
