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:

What might I write? How about:
