 Description: This command will tell the ESP32 to re-enable its idle animation. It will respond with a `!3;` when it recieves this command.
 
-**HERE IS A GUIDE TO GET YOU STARTED ON YOUR [MAYBE] FIRST REPOSITORY**:
-
-<https://docs.codeberg.org/getting-started/first-repository/#2.-clone-the-repository>
-
-Obviously, this is not what your README should say on-submission. Change it. Yes, the whole thing.
-
-This is where a description of your project will go. README.md files support [Markdown syntax](https://www.markdownguide.org/basic-syntax/).
-
-## Setup
-
-**Oh yeah, by the way, don't forget to set up `git lfs` on your machine.**
-
-Tell everyone what your project needs in order to run. This might involve many components or software. Maybe some cool libraries?
-
-### Hardware Required
-
-- Some polyphonic headset on OS version `3.14159265358979323846233832795028841971` with room-temperature hyperconductors
-- Some macrocontroller with specific hardware revision `4.2`
-  - With tank wheels
-- Some computer with a holoported underdisplay cap
-- Some fancy smart device that is worn and knows your favorite toothpaste
-
-### Software Dependencies
-
-- Division Game Engine version `2024.1.26`
-- Michaelsoft Binbows `XD`
-
-## Run
-
-1. Open the thing
-   - You know, that thing over there
-     - No, not that one
-     - Go back
-     - Yes, that one
-2. Click the button and type the following text:
-
-```shell
-# install the sotware
-sudo apt install -y cmatrix
-# run the trap
-cmatrix
-```
-
-3. After the process completes and you don't even see the code, anymore, you are ready. Here is what it looks like:
-
-```js
-"b" + "a" + +"a" + "a"; // 'baNaNa'
-```
-
 ## Shout-Outs
 - Thank you to all the organizers at Reality Hack and the Hardware track.
 - Lucas De Bonet for creating `the Singularity` which allowed us to connect the board to Quest headsets.
