+## Protocol info
+This info was gathered from the respecctive locations in the firmwares comments.
+Ie. lib/infrared/encoder_decoder/`*`/infrared_protocol_`*`.h
+Some of the info doesn't show up well so view thew raw readme or [this commit](https://github.com/flipperdevices/flipperzero-firmware/commit/75e9de12b065bd5e572b8b9232c8b9670c8e6f91).
