+## Releasing a new Primer version 🎉
+
+
+### In `primer/primer`:
+
+1. Create a new release branch from `dev` and name it `release-<version>`.
+
+ (CI will publish a release candidate version to npm for branches prefixed with `release`. These version numbers have a `rc.<number>` suffix on them)
+
+2. Go through the tracking issue and make sure everything that should be merged in is merged in.
+
+3. Once your builds finishes, click on the details links for the continuous-integration/travis-ci/push build.  Expand the `Deploying application` output and you should be able to find an outputted change log here. Copy this and update the CHANGELOG.md file in `primer`.
+
+4. Run the version bump in your command line: `npm run bump`.
+
+5. Test your changes with the latest release candidate version in the appropriate places (styleguide, storybook, github/github).
+
+6. Once the release PR is approved and you've done necessary testing, merge to `master`. This will trigger a publish to npm.
+
+
+### In `github/github`:
+
+1. Create a new branch
+
+2. Update the primer version  `npm install primer@<version>`.
+
+3. Update `stylelint-config-primer` to the appropriate version.
+
+4. If you need to make changes to github/github due to the Primer release, make a separate branch. When ready, merge that branch into your release branch.
+
+5. Add reviewers.
+
+6. Check that every deleted vendor file has an accompanying updated vendor file and that the version numbers look correct.
+
+7. Test on review-lab.
+
+8. When ready, merge! 🎉
+
+
