Open the Minecraft Launcher and ensure you have selected the 'forge' profile from the dropdown.
Click the 'Mods' dialog box and verify whether or not you have installed the circuitry mod.
(If the mod is not installed, head on down to the manual installation instructions and that should get you up and running)
Manual Installation Instructions
"Because sometimes, things happen"
Purchase the Minecraft: Java Edition from minecraft.net/en-us/store/minecraft-java-edition. It is imperative that you do not purchase any version other than the Java Edition. Our class framework only functions with the Java Edition of the game.
Download your copy of Minecraft: Java Edition from minecraft.net/en-us/download. Minecraft is available for Windows, MacOS, Debian Linux, and Arch Linux. (Side note: we cannot guarantee full functionality of this modification on Arch Linux. If you are running Arch or another distribution, please contact an instructor via Discord or ELMS.)
Run the Minecraft: Java Edition launcher at least once. Ensure that you can log in using the account you created, thusly verifying your purchase went through. This will ensure that it generates the required program files for our mod to properly interact with. Do not skip this step!
