Make example for this keyboard (after setting up your build environment):
- make handwired/xealous-brown:default
+ make handwired/xealousbrown:default
+
+The brief list of speedhacks to make this keyboard blazing fast:
+1) bit-bash implementation of scanning rows, columns. Very short delay between pin waiting.
+2) Compiling with a few extra flags
+3) Eager-per-key Debouncing algorithm (no 5ms delay before message is sent)
+4) 1000hz polling
