 # Raspberry Pi Pico SDK
 
 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
+necessary to write programs for the RP-series microcontroller-based devices such as the Raspberry Pi Pico or Raspberry Pi Pico 2
 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 RP-series microcontroller's hardware including 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.
+Additionally, the SDK provides higher level libraries for dealing with timers, synchronization, Wi-Fi and Bluetooth networking, USB and multicore programming. These libraries should be comprehensive enough that your application code rarely, if at all, needs to access hardware registers directly. However, if you do need or prefer to access the raw hardware registers, you will also find complete and fully-commented register definition headers in the SDK. There's no need to look up addresses in the datasheet.
 
-The SDK can be used to build anything from simple applications, to fully fledged runtime environments such as MicroPython, to low level software
-such as RP2040's on-chip bootrom itself.
+The SDK can be used to build anything from simple applications, fully-fledged runtime environments such as MicroPython, to low level software
+such as the RP-series microcontroller's on-chip bootrom itself.
+
+The design goal for entire SDK is to be simple but powerful.
 
 Additional libraries/APIs that are not yet ready for inclusion in the SDK can be found in [pico-extras](https://github.com/raspberrypi/pico-extras).
