@@ -90,6 +90,15 @@ Here are some general principals you should try to adhere to:
 * No dynamic memory allocation, except during setup/begin functions.
 * Use the same brace and indenting style that's in the core source modules. (A .clang-format is prob going to be added soon, but please do NOT retroactively re-format existing code. This just creates unnecessary diffs that make finding problems harder)
