I think this is a great idea and will like this to be implemented. Github knows when a contributor is new and we can use this information to give more detailed instructions.

The "Be patient." at the end sounds very aggressive. I would go for something like "thank you for your patience" instead 😅

Sorry for making you wait, here a last few rephrasing suggestions:

if steps or assets -> if **specific** steps or assets
The time it may take -> The time it will take
could vary -> may vary
to see if some fixes have been made -> to track new fixes

And I concur with Emi on Thank you for your patience.

Done! Thanks @MurderVeggie and @AThousandShips for your reviews. I set the PR as ready, as all changes were implemented.

LGTM, can't tell if anything is missing though, but what's there is great!
