I'm not very good at making tutorials so you'll have to forgive me.

Requirements:
Guitar Hero World Tour (idk if AiO [All in One] will work)
Guitar Hero SDK (https://gitgud.io/fretworks/guitar-hero-sdk)

Installation:
Follow what it says on here
https://gitgud.io/fretworks/guitar-hero-sdk/-/wikis/Installing-GHSDK

after installing GHSDK go to:
C:\Program Files (x86)\Aspyr\Guitar Hero World Tour
or where ever you installed GHWT

go into GHWTBaseMod, UserContent.

If there is no "Characters" Folder make one.
after doing that place "MKAScorpion" in the folder.

after doing that go to

C:\Users\----\guitar-hero-sdk

Right click and click on "Git Bash Here"

type in without the quotation marks "node sdk.js"

Go to scripting, go down to "qb" and press enter on compile

after doing that go to "Packaging"

Press enter on "band_mode" then select "Pack + Sync"

Repeat this step for the other 4 ones:

cas_ui
grskel_custom
grskel_custom_orig
qb

Then your done.
