Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept your contribution by verifying you have signed the PSF contributor agreement (CLA).

Unfortunately we couldn't find an account corresponding to your GitHub username on bugs.python.org (b.p.o) to verify you have signed the CLA (this might be simply due to a missing "GitHub Name" entry in your b.p.o account settings). This is necessary for legal reasons before we can look at your contribution. Please follow the steps outlined in the CPython devguide to rectify this issue.

You can check yourself to see if the CLA has been received.

Thanks again for your contribution, we look forward to reviewing it!

LGTM. Please sign the CLA. Thanks.

@tirkarthi I did, or at least believe I have (got an email confirmation of it being signed). Does it take a while for gh to pick that up?

[tirkarthi]

It might take a couple of days from my experience and the bot will change the label automatically after that.

Thank you for your contribution @alanag13!

Trivial doc changes do not need signing the CLA.
