-- Tested on Raspberry Pi 4 Model B and Raspberry Pi 3 Model A+, B, and B+.
+- Supports Raspberry Pi Zero 2 W, Raspberry Pi 3 Model A+, B, and B+, Raspberry Pi 4 Model B, and CM4 series.
   * Pi 2 works, but only with concessions on playback quality.
-  * Pi Zero and 1 are unfortunately too slow (even with an overclock) and unsupported.
+  * Pi Zero (original) and Pi 1 are unfortunately too slow (even with an overclock) and unsupported.
 - PWM headphone jack audio.
   * Quality is known to be poor (aliasing/distortion on quieter sounds).
   * It is not currently known whether this can be improved or not.
