    It generates all release binaries under the directory `/tmp/etcd-release-${VERSION}/etcd/release/` and images. Binaries are pushed to the Google Cloud bucket
    under project `etcd-development`, and images are pushed to `quay.io` and `gcr.io`.
 7. Publish the release page on GitHub
-   - Set the release title as the version name
-   - Choose the correct release tag (generated from step #4)
-   - Follow the format of previous release pages
-   - Attach the generated binaries and signature file
-   - Verify the historical binary size for each architecture. If there's a big difference, verify that it works for that architecture
-   - Select whether it's a pre-release
-   - Publish the release
+   - Open the **draft** release URL shown by the release script
+   - Review that it looks correct, then publish the release
 8. Announce to the etcd-dev googlegroup
 
    Follow the format of previous release emails sent to [email protected], see an example below. After sending out the email, ask one of the mailing list maintainers to approve the email from the pending list. Additionally, label the release email as `Release`.
