Today I tried to contribute to CPython. My pull request was small and changes minor, I found a mistake in HAMT algorithm description in the comments.
After sending my pull request and my username was checked by the bot "the-knights-who-say-ni", and the bot said the next message with "CLA not signed" badge.
I was really surprised. Despite this my fix was accepted and merged.
But here are the steps needed in order to sign the CLA (from https://devguide.python.org/pullrequest/#licensing
