+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.
 
 The SDK  is designed to provide an API and programming environment that is familiar both to non-embedded C developers and embedded C developers alike.
 A single program runs on the device at a time and starts with a conventional `main()` method. Standard C/C++ libraries are supported along with
-C level libraries/APIs for accessing all of the RP2040's hardware include PIO (Programmable IO)
+C level libraries/APIs for accessing all of the RP2040's hardware include PIO (Programmable IO).
 
 Additionally the SDK provides higher level libraries for dealing with timers, synchronization, USB (TinyUSB) and multi-core programming
 along with various utilities.
 
-The SDK can be used to build anything from simple applications, full fledged runtime environments such as MicroPython, to low level software
-such as RP2040's on chip bootrom itself.
