 For code submissions based on reverse engineered binary functionality, please either reverse engineer functionality from MIT Licensed Espressif releases or make sure that the reverse engineered code does not directly copy the code structure of the binaries - it cannot be a "derivative work" of an incompatible binary.
 
-The best way to write suitable code is to first add documentation somewhere like the [esp8266 wiki](https://github.com/esp8266/esp8266-wiki/) describing factual information gained from reverse engineering - such as register addresses, bit masks, orders of register writes, etc. Then write new functions referring to that documentation as reference material.
