 # Description
-This is R0b3's Discord Bot.  It's creation was basically a challenge posed a coworker who said "Hey, you can write Discord Bots in Python... Make one to display your 3D printer status!".
+This is R0b3's bot, originally built as a Discord bot to display 3D printer status. It now also runs as a Matrix bot, both operating simultaneously in the same process.
 
 # Features
-*  Query & Monitor OctoPrint 3D Printer Status using the `$printstat` command (Requires that your printer is connected to [Octoprint](https://octoprint.org/))<br>
+* Query & Monitor OctoPrint 3D Printer Status using the `$octostat` command (Requires that your printer is connected to [Octoprint](https://octoprint.org/))<br>
 ![](images/Discord_Printstat_Command.png)
-*  Query & Monitor Bambu Lab Printer Status using the `$bambustat` command (Requires a Bambu Lab printer accessible on the local network via MQTT)<br>
-   *  Displays print state, progress percentage, time remaining, current layer, bed temp, nozzle temp, and chamber temp
-   *  Optionally captures and attaches a camera snapshot from the printer's RTSPS stream (requires [ffmpeg](https://ffmpeg.org/) on the host)
-   *  Updates the bot's Discord status to show live Bambu print progress while a print is running
-*  Play a selection of sound clips to voice channel members using the various commands (`$torololo`, `$oops`, `$promoted`, etc)
+* Query & Monitor Bambu Lab Printer Status using the `$bambustat` command (Requires a Bambu Lab printer accessible on the local network via MQTT)

+  * Optionally captures and attaches a camera snapshot from the printer's RTSPS stream (requires [ffmpeg](https://ffmpeg.org/) on the host)
+  * Updates the bot's Discord status to show live print progress; alternates between OctoPi and Bambu status every 30 seconds when both printers are running simultaneously
+* Query both printers at once using the `$printstat` command
+* Play a selection of sound clips to voice channel members using the various commands (`$trololo`, `$oops`, `$promoted`, etc) — Discord only
+* **Matrix support** — the bot can connect to a self-hosted Matrix homeserver (Synapse/Dendrite) and respond to the same text commands in E2E-encrypted rooms
 
 # Commands
 ![Screenshot of $help](images/command_list.png)
