+
+Make example for this keyboard (after setting up your build environment):
+
+ make rainkeebs/trailmix:default
+
+Flashing example for this keyboard:
+
+ make rainkeebs/rainkeeb:default:flash
+
+(Flash one side of the keyboard at the time)
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
