 A typical release cycle goes like this:
 1. When a commit is pushed to the React repo, [GitHub Actions](https://github.com/facebook/react/actions) will build all release bundles and run unit tests against both the source code and the built bundles.
 2. Each weekday, an automated CI cron job publishes prereleases to the `next` and `experimental` channels, from tip of the main branch.

 ## Publishing Without Tags
 
 The sections below include meaningful `--tags` in the instructions. However, keep in mind that **the `--tags` arguments is optional**, and you can omit it if you don't want to tag the release on npm at all. This can be useful when preparing breaking changes.
