-There is a release script at `dev-bin/release.sh` that will do the full
-release, including updating the GitHub Pages site.
-
-This script reads the VERSION number from `CHANGELOG.md`, which you should
-have updated to contain the new version number and today's date. After
-uploading with this script, you will need to perform the release on the
-[Sonatype OSS site](https://oss.sonatype.org/index.html).
-
-We release to the Maven Central Repository through Sonatype OSSRH. They
-provide [detailed directions](https://central.sonatype.org/pages/apache-maven.html)
-on the steps of the release or snapshot release process.
-
-All releases should follow [Semantic Versioning](https://semver.org/).
-
-Steps for releasing:
-
-1. Review open issues and PRs to see if any can easily be fixed, closed, or
-   merged.
-2. Bump copyright year in `README.md`, if necessary.
-   * You do not need to update the version. The release script will do so.
-3. Review `CHANGELOG.md` for completeness and correctness. Update its release
-   date. Commit it.
-4. Install or update [gh](https://github.com/cli/cli) as it used by the release script.
-5. Test that `mvn package` can complete successfully. Run `git clean -dxff`
-   or something similar to clean up afterwards.
-6. Run `./dev-bin/release.sh`.
-   * This will package the release, update the gh-pages branch, bump the
-     version to the next development release, upload the release to GitHub
-     and tag it, and upload to Sonatype.
-   * It may prompt you about out of date dependencies. You should consider
-     updating them if appropriate. Say no and review the changes and upate
-     `pom.xml` and start the release process over again if you do.
-7. The `nexus-staging-maven-plugin` will automatically promote the release on Sonatype.
-
-There is more information in the
-[minfraud-api-java](https://github.com/maxmind/minfraud-api-java/blob/main/README.dev.md)
-`README.dev.md` about doing a Java release, including setting up your
-environment and completing the release on Sonatype.
+See the [`README.dev.md` in `minfraud-api-java`](https://github.com/maxmind/minfraud-api-java/blob/main/README.dev.md).
