+## Usage
+
+Installation:
+1. Include the header file `as5600.h` and source file `as5600.c` in your C/C++ code.
+2. Ensure that the required dependencies are installed, such as the STM32 HAL library or any other libraries specific to your STM32 development environment.
+
+Usage:
+1. During the boot of your application initialize I2C driver and then call `as5600Init()`
+2. Periodically (with rate 10 Hz) call `as5600CollectData()`. If it returns `LIBPERIPH_OK`, then call `as5600ParseCollectedData()`.
