 This is a micro-ROS library for baremetal projects based on Arduino IDE or Arduino CLI.
 
-As the build process for ROS 2 and micro-ROS is based on custom meta-build system tools and [CMake](https://cmake.org/), this library is provided as a precompiled library. However, users can rebuild their own precompiled libraries in order to modify the micro-ROS configuration or [RMW parameters](https://micro.ros.org/docs/tutorials/advanced/microxrcedds_rmw_configuration/) by customizing the respective [.meta file](https://github.com/micro-ROS/micro_ros_arduino/tree/main/extras/library_generation).
