User:Enterprisey/USinstall

Hint: It's much easier if you get ScriptInstaller, then navigate to User:Enterprisey/USinstall.js and click "Install" at the top.

However, here's the manual method:

1. Place {{subst:iusc|User:Enterprisey/USinstall.js}} on Special:MyPage/common.js or a skin-specific page, like Special:MyPage/vector.js.
2. Clear your cache and enjoy!
