+# The split-space HHKB keymap for co60
+
+This keymap implements a modified MX HHKB layout, but in addition to 7u space,
+this layout supports a number of split spacebar bottom rows. The full set of
+layout options is found
+[here](http://www.keyboard-layout-editor.com/#/gists/b488496b3a71c8192113c07e298be340).
