+![oem_ansi_fullsize](https://imgur.com/a/Tw7dwK4)
+This is a basic layout for a full-sized ANSI board. It should be compatible with any 100% full-sized layout, for example [RobotDoctor's MECH-104](https://www.thingiverse.com/thing:4205065).
+
+* Keyboard Maintainer: [Cian Johnston](https://github.com/johnstcn)
+* Hardware Supported: Teensy®++ 2.0 as it has enough pins for the matrix.
+* Hardware Availability: [pjrc.com](https://www.pjrc.com/store/teensypp.html)
+
+The pin layout I used is shown below. Change it as you wish, but be sure to avoid pin D6!
