 * Adafruit_BBIO is a set of Python tools to allow GPIO, PWM, and ADC access on the BeagleBone
 
 * It is recommended to use an [official BeagleBoard.org Debian image](https://beagleboard.org/latest-images)
-  * Currently recommended image: [Stretch Snapshot iot (2017-10-29)](https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#microSD.2FStandalone:_.28stretch-iot.29_.28All_BeagleBone_Variants_.26_PocketBeagle.29) with [Linux kernel](https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Kernel_Options) [4.14.0-rc7-ti-r6](https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Mainline_.284.14.x_lts.29)
-    * note: Cloud9 IDE is now fully compatible with Adafruit_BBIO as udev is configured to enable non-root control of GPIO and PWM _(refer to commit [b65cbf8](https://github.com/adafruit/adafruit-beaglebone-io-python/commit/b65cbf8e41b444bad7c4ef6cfd4f88a30210fd78))_
