Ask HN: Can you help me find a previous HN post?

So I read a post here earlier this year which was so useful, but I can't find it again despite spending hours searching on HN and my browser history.

Any chance you can help me find the post I'm talking about? Christmas cheer and all that!

This is what I remember about the post - the post linked to a long Google Doc which was a guide of how to run a startup - there was lots of advice on how to run different meetings eg. team meetings, 1:1s etc - the Google Doc was created by an executive/CEO/startup coach with lots of experience - the post was created in 2018

Any ideas? Any help would be massively appreciated
