Default branch is dev. You should set dev as the target branch of PRs. We will merge dev into main regularly.
main branch is the release branch, which means all content in this branch will be directly consumed by the Office Add-ins Development Kit's sample gallery:

- Add a new project folder under root directory.
- Make sure it's runnable and well tested.
- Add README.md and RUN_WITH_EXTENSION.md. You can use the README_TEMPLATE.md under root directory.
- Add a new config to the config file with following format.
