Manager READMEs have been an on-again, off-again thing over the last few years. The negatives are mostly because the author can't see their own weaknesses and over-value their strengths. Many readmes are long and rambling. Mike Crittenden suggests, instead, writing a 50-word personal readme:

You get 50 words, that’s it. It’s a forcing function to kill the fluff and decide what people must know about you.

What might I write? How about:

• Written over verbal
• Long-term over short-term
• I offer trust first
• Don't lie to me
• Bad news doesn't age well
• Team over individual
• Remote-first
• We're professionals and adults

Well, that's 30 words for now, anyway.
