Wow, really cool. I feel like using Github like this could really take off. Free storage and compute and scheduling. I'm definitely going to keep this in mind for any future fun projects--it seems like a scraper is an obvious use case.
For anyone interested in trying this, you need to set the ENV var `CONTRIBUTORS_TOKEN` with your github API token, then create a README.md with the following sections:
### [{project}](https://github.com/{owner}/{project}/)
<!-- contributors-{project} starts -->
contirbutors will be auto-populated here
<!-- contributors-{project} ends -->
with the {owner} and {project} replaced, then after running authors.py the README will get auto-populated.
