+This is a custom firmware being developed for the [LilyGo T-Deck](https://www.lilygo.cc/products/t-deck), currently it is experimental & buggy while we are in beta status.
 
-I am terrible at C++ and still am trying to wrap my head around the language's logic, so most of this code has been shit out and written like a cowboy.
+If you are familiar with or use [Internet Relay Chat](https://en.wikipedia.org/wiki/IRC), we have a team of developers working on this project in **#comms** on **[irc.supernets.org](irc://irc.supernets.org)**, join us if you have ideas, bugs, or want to get your hands dirty & develope this project with us.
 
-The project started out with as IRC bridge for [Meshtastic](https://meshtastic.org/) over MQTT, just so I could say "we have IRC over radio", which later led to me modifying the official Meshtastic [firmware](https://github.com/meshtastic/firmware) to add extended features. I am deep in the rabbit hole of embedded development and am starting from scratch making this an entirely custom firmware.
+Consider sponsoring our project, all the money goes towards motivation to develope on this, we also like buying T-Decks for people who want to learn about this stuff!
 
-This is being developed in my free time as a fun project. It is no where near being useful.

-A compiled "release" will be done once I finish somoe fo the basic features, but feel free t compile this on your own to test it out!

-# Known issues
+# Ideas
-- Messages that exceed the screen width and wrap to the next line will throw off thje logic of calculating the max lines able to be displayed on the screen. Messages eventually go off screen.
+- Replace the `ESP32-S3FN16R8` with a `ESP32-S3-WROOM-1U` which has an iPex connector for an external WiFi antenna.
-- Input messages exceeding the screen width go off screen, and need to wrap and create a new input line, pushing up the backlog of messages.
-- Some colors are not working when its only a background color or only contains a space
-- Sometimes it will not connect to IRC even from reconnections, and you have to reboot and try again.
-- Screen timeout can occur during an IRC reconnection and blck keyboard input
