* initial check in * figure out the column pins * temporary keymap * guess the row pins * fix matrix.c compilation errors * use the LAYOUT_60_hhkb macro and tweak the keymap a little bit * update readme * Put my name everywhere * Add QMK Configurator support * figured out the row pins * update readme to have reset info * Fill in some blanks that are documentation related * Update matrix.c * add kb functions * forego kbfirmware labeling * add arrows and caps lock to function layer. * add a LAYOUT_60 and LAYOUT_all macro * missed a comma * add configurator support for the two new LAYOUT macros * Jack helped me with a new custom matrix * add 60_ansi into rules.mk
