Awesome! Thanks for fixing this @khorne3 🎉

[khorne3]

oops @jsjoeio not sure if that merged to the right place; please let me know if I need to revert so we can fix

[jsjoeio]

@khorne3 i'll let you decide. before it was in FAQ, now you have it in Guide. Totally up to you!

[khorne3]

@jsjoeio ah sorry for the confusion; I just saw that you added it to 3.12.0 milestone and wasn't sure if this is ok to go into main?

[jsjoeio]

Oh! It's okay to go into main. 3.11 was already released so that's why I added it to 3.12. We use the milestones to associate issues/PRs that were done in that cycle. Sorry for the confusion!
