You can see how to do it from the readme on the repo: https://github.com/CommunityToolkit/Maui

I thought we had this information on our docs page but I can’t see it.

There is nothing about it as well: Microsoft

Not sure how this info got missed. I’ll add it to the getting started section. Although you should have seen a readme file open when you added the package informing for the required steps. I know some of the team are adding an analyser to inform devs when they haven’t done this

@8m0 you need to call UseMauiCommunityToolkit in your MauiProgram file
