+
+## Checklist for Adding a New Language**
+
+Before submitting your pull request, please ensure the following requirements are met:
+
+- [ ] I have added the language to `syntax.json` with the language name matching that in GitHub's [Linguist `languages.yml` file](https://github.com/github-linguist/linguist/blob/main/lib/linguist/languages.yml).
+- [ ] I have added sample code to `test_new.diff` and `test_closed.diff`.
+- [ ] I have added issue creation and closure tests to `test_todo_parser.py`. The test should check that the `ace_mode` of the issue matches that specified in the `languages.yml` file. If an existing check for that `ace_mode` exist, I have incremented that instead.
+- [ ] I have updated the README to add the language.
+- [ ] I have run and verified all tests.
+
+## Thank You!
