-## Release Process
+## Publish
 
-To release a new version, make sure that everything works. Then run `yarn version` and bump the version number. Lastly, push to GitHub (with the release tag). [Travis](https://travis-ci.org/vega/vega-tooltip/builds) will build a bundle and make the [npm release](https://www.npmjs.com/package/vega-tooltip) automatically.
+Publishing is handled by a 2-branch [pre-release process](https://intuit.github.io/auto/docs/generated/shipit#next-branch-default), configured in `publish.yml`. All changes should be based off the default `next` branch, and are published automatically.
+
+- PRs made into the default branch are auto-deployed to the `next` pre-release tag on NPM. The result can be installed with `npm install vega-tooltip/@next`
+- To release a new stable version, open a PR from `next` into `stable` using this [compare link](https://github.com/vega/vega-tooltip/compare/stable...next).
