After installing Minecraft Launcher and Minecraft Java

- close it all

- double click on "fabric-installer-1.1.1"
- install fabric (basically click through and make sure the version is for 1.21.11)

- press "Win+r"
- type "%appdata%" and press enter
- double click on ".minecraft"
- move contents from inside these folders (mods, resourcepacks, shaderpacks) to the folders in .minecraft.

- open the Minecraft Launcher
- check the bottom left corner for it to say "fabric-loader-1.21.11...."

TIP: I go to Installations at the top, select "..." to the right of fabric-loader-1.21.11, select Edit, select MORE OPTIONS, and in the JVM arguments increase the -Xmx2G to a little more. (I've got 32gb of ram in my system so I put it at -Xmx8G).
click Save and start the game!
