* Requests need not be a single commit, but should be a linear sequence of commits (i.e. no merge commits in your PR)
* It is desirable, but not necessary, for the tests to pass at each commit
* Have clear commit messages
* e.g. "Refactor feature", "Fix issue", "Add tests for issue"
* e.g. "Minor refactor in goToTypeDefinition", "Fix iterated type in for-await-of", "Add test for preserveWatchOutput on command line"
