 # Raspberry Pi Pico SDK
 
+> **FORK NOTE**
+> This fork of the Pico SDK has the TinyUSB library upgraded to allow more CDC chips. 
+> Once the TinyUSB library makes its next release, and the pico sdk incorporates that, 
+> it's a good idea to **switch back to the original**.

 The Raspberry Pi Pico SDK (henceforth the SDK) provides the headers, libraries and build system
 necessary to write programs for the RP2040-based devices such as the Raspberry Pi Pico
 in C, C++ or assembly language.
