 # Adafruit-PiTFT-Helper
 
-A script for configuring Adafruit's PiTFT displays on a Raspberry Pi.
+### This script/repository is deprecated, as trying to do kernel updates on the fast-moving Raspberry Pi wasn't sustainable! We're now using a simpler device-tree-only script, available at https://github.com/adafruit/Raspberry-Pi-Installer-Scripts/blob/main/adafruit-pitft.py
+
+We'll keep this repo public but archived for the curious.

+---------------------------------

+A (deprecated) script for configuring Adafruit's PiTFT displays on a Raspberry Pi.

+## Attention RETROPIE Users:
+
+Do not use the adafruit-pitft-helper script with RetroPie. Instead, follow the directions on this page:

 ...where `-t` specifies the type of PiTFT just like the same option to
 `adafruit-pitft-helper`, and `-i` specifies the path to an image file.
 
+You can also use [`adafruit-pi-chroot`][pi-chroot] to run a `chroot`ed shell
+inside of a Raspbian ISO image.  Like the install wrapper, this relies on
+`kpartx`.
+
+These are the scripts we use to produce the Easy Install images offered in
+Adafruit product documentation.  They may be a bit rough around the edges.
+
+## Older Versions
+
+For the version supporting Raspbian Wheezy, check out the `wheezy` branch
+on this repository.
