 By publishing prereleases to the same registry that we use for stable releases, we are able to take advantage of the many tools that support the npm workflow, like [unpkg](https://unpkg.com) and [CodeSandbox](https://codesandbox.io).
 
-### Latest Channel
+### Latest Channel {#latest-channel}
 
 Latest is the channel used for stable React releases. It corresponds to the `latest` tag on npm. It is the recommended channel for all React apps that are shipped to real users.
 
 **If you're not sure which channel you should use, it's Latest.** If you're a React developer, this is what you're already using.
 
 You can expect updates to Latest to be extremely stable. Versions follow the semantic versioning scheme. Learn more about our commitment to stability and incremental migration in our [versioning policy](/docs/faq-versioning.html).
 
-### Next Channel
+### Next Channel {#next-channel}
 
 The Next channel is a prerelease channel that tracks the master branch of the React repository. We use prereleases in the Next channel as release candidates for the Latest channel. You can think of Next as a superset of Latest that is updated more frequently.

 Experimental features are ones that are not ready to be released to the wider public, and may change drastically before they are finalized. Some experiments may never be finalized -- the reason we have experiments is to test the viability of proposed changes.
 
 For example, if the Experimental channel had existed when we announced Hooks, we would have released Hooks to the Experimental channel weeks before they were available in Latest.
 
 You may find it valuable to run integration tests against Experimental. This is up to you. However, be advised that Experimental is even less stable than Next. **We do not guarantee any stability between Experimental releases.**
