+About
+------
+
+First pass at adding support for the gherkin keyboard. Compiles but completely
+untested. Intended to kick-start development.
+
+* [Gherkin project on 40% Keyboards](http://www.40percent.club/2016/11/gherkin.html)
+* [The original TMK firmware](https://github.com/di0ib/tmk_keyboard/tree/master/keyboard/gherkin)
+
+Credit to JadedC for the initial work.
