 # WiringPi Library
+
 Welcome to the WiringPi Library, the highly performant GPIO access library for Raspberry Pi boards. This library is written in C and is designed to provide fast and efficient control of the GPIO pins by directly accessing the hardware registers using DMA.

+**Key Features:**  
+
 - **Support:** WiringPi supports all Raspberry Pi Boards including Pi 5 ( :construction: On the Pi 5, only the GCLK functionality is currently not supported due to missing documentation of the RP1 chip).
 - **High Performance:** By directly accessing the hardware registers, WiringPi ensures minimal latency and maximum performance for your GPIO operations.
 - **Wide Adoption:** WiringPi is widely used in numerous projects, making it a reliable choice for your Raspberry Pi GPIO needs.

 :information_source:️ Since 2024, [GC2](https://github.com/GrazerComputerClub) has taken over maintenance of the project, supporting new OS versions as well as current hardware generations. We are dedicated to keeping the arguably best-performing GPIO Library for Raspberry Pi running smoothly. We strive to do our best, but please note that this is a community effort, and we cannot provide any guarantees or take responsibility for implementing specific features you may need.
