I don't know how to use Git.

grape

A Miiverse clone, named which due to Miiverse's original codename being 'olive'. Heavy work in progress. There is a lot of naive programming in here, I'm new to PHP and it'll get better soon.

grp_portal

This is portal, or the Wii U mode.

grp_offdevice

The offdevice version. This was written when I knew more PHP then when I had written portal. It's way better written, and I'm trying to rewrite portal now.

grplib

This will be a shared library to be used between 3DS and off-device.

How to install???

First, use nginx, since that's the best web server software. I'm kidding, but it's really good. Set up however many servers you want. You must have separate servers for each realm and cannot have them in directories of your site. If you want to set up portal, make its root grp_portal-php, and the same for offdevice. Make a database in MySQL, then make a new config.php from the template and connect to your DB. Run db_create.sql in whatever you use as an interface to MySQL, and it'll work.

Rewrites (nginx)

These are required, you cannot use the .php files directly or you might get a 404 and JS won't work.
