 # gpio\_control: a ROS package for reading/writing GPIO states on the Pi, Jetson, and many more
 ## Overview
-_This package is currently unstable and in testing_
-
 Devices such as the Raspberry Pi, NVidia Jetson, BeagleBone Black, etc have GPIO pins as an additional set of IO,
 which can be toggled between high/low states or configured to read high/low inputs. This package allows for
 ROS control of these pins, allowing for configuring each pin as desired and then reading/writing

 The `gpio_control_node` operates by providing a command line interface to the `gpio_control_utils`
 python package, which will be importable in other projects upon installation. This provides a
 standard and stable interface for reading and writing to GPIO pins. See the node for example
