 The project is composed of customizing the 2nd stage bootloader from IDF and UF2 factory application as 3rd stage bootloader.
 
 **Note**: IDF is actively developed and change very often, TinyUF2 is developed and tested with IDF v5.3.2. Should you have a problem please try to change your IDF version.

 ## Requirements
 
 This guide focuses on building TinyUF2 for Analog Devices' MAX32 parts.
 It is written with Windows users in mind using the **MSDK**, but TinyUF2 is fully portable and can be built with a standard toolchain on Linux and macOS.
