How to add a new statement

To add a new statement for one of the therorems, do not modify index.html directly because it is automatically generated. Instead, edit statements.yml. Then, if you have node installed, generate the index file with gen.js > index.html and check it looks as intended in a browser. Finally, make a pull request with both files.

If the proof does not belong to another repository, you can also add a single self-contained .v proof file, in which case you should edit LICENSE.md accordingly.
