Step 1: Download Forge

You'll need Minecraft Forge for 1.12.2 to run TekTopia

Go to https://files.minecraftforge.net/ and install the 1.12.2-14.23.5.2768 version.

Windows users can simply download and run the Windows Installer.

Step 2: Install Forge

Select "Install Client" and make sure the installation path matches where Minecraft is installed on your computer. For most Windows users this will be

C:\Users\YourUserName\AppData\Roaming\.minecraft

Step 3: Run Forge Minecraft Once

Installing Forge creates a new launch profile in the Minecraft Launcher.

Run that new profile once (You don't need to launch a world, just the game). This creates the folder you'll add mods to.

Step 4: Navigate To Your Minecraft Folder

Navigate to your Minecraft installation folder. You can easily find it by launching Minecraft, going to Options->Resource Packs->Open Resource Packs Folder, then go up one level.

If you have not customized your Minecraft installation, you may also find your profile folder at %appdata%\.minecraft on Windows, ~/Library/Application Support/minecraft on macOS, or ~/.minecraft on Linux

Step 5: Add Mods to the Mods Folder

Download the latest TekTopia jar file and save it to the "mods" folder in your Minecraft folder.

TekTopia can be downloaded here:

Step 6: Enjoy

You've installed TekTopia! Launch the forge profile in the Minecraft launcher you made earlier and get playing!
