In my opnion, this Hall of Fame is to showchase things that Github enables or highlights. I'm generally looking for anything that could be described as epic.
Pull requests, issues, and comments are great examples, since Github's UI enables or highlights these interactions in otherwise boring source control.
Individual Commits also seem fine to me because really, Github is the reason we have nice access to epic diffs.
It makes less sense to me to submit an entire project, because the project could exist anywhere.
These are somewhat loose guidelines. As more precedents are set, they may be modified. Feel free to explain why something deserves to be in the Hall of Fame when you submit PRs.
Add an entry to _data/entries.yml in the same format as the others.
Pretty straightforward, but feel free to raise any issues of this format
doesn't capture something you would like to submit!
Also feel free to ask on Twitter at @mehulkar.
