Installing mods on the launcher version of Dungeons:
1. Press Win + R, enter %localappdata%\Mojang\products\dungeons\dungeons\Dungeons\Content\Paks and press Ok
2. Make a new folder called `~mods` and put your mods in this folder

Launch the game through `%localappdata%\Mojang\products\dungeons\dungeons\Dungeons.exe`, I recommend creating a shortcut for it.
*Launching the game through the launcher will remove any mods you have*


How to set up the Windows Store version of Dungeons for modding:
1. Enable Developer mode by pressing Win + R, enter `ms-settings:developers`, click Ok, and then click on Developer mode
2. Download UWPDumper: <https://github.com/Wunkolo/UWPDumper>
3. Start Minecraft Dungeons and wait until the window appears
4. Start UWPInjector (from the UWPDumper download) and enter the number next to Dungeons.exe in the list that appears
5. Press Win + R, enter `%localappdata%\Packages\Microsoft.Lovika_8wekyb3d8bbwe\TempState` and press Ok
6. Move the DUMP folder to anywhere you want, you can also rename it if you want to
7. Replace the appxmanifest.xml file in your folder with this one: https://cccode.bitbucket.io/dungeons/appxmanifest.xml (if you open the link in Chrome, right click on the page and click `Save as...`)
8. In the folder, click in the address bar at the top and enter `powershell` and then press enter
9. Run this command in PowerShell: `Add-AppxPackage -path .\appxmanifest.xml -register`

This will register an app called "Minecraft Dungeons [Modded]". Run this app instead of the normal Dungeons app when you want to play with mods.
Install any mods into `Dungeons\Content\Paks\~mods` in the folder you moved/renamed. If you don't have a `~mods` folder, just create one.
