 ## Updating to the latest upstream tailwindcss version
 
-Update `lib/tailwindcss/ruby/upstream.rb` with the upstream version.
+Please don't submit PRs to the maintainer with an upstream bump.
 
-Run `bundle exec rake clobber` then `bundle exec rake download` to ensure the tailwindcss binaries can be downloaded, and that you have the correct versions on local disk.
+- [ ] run `bin/bump-upstream`
+- [ ] push the branch, create a PR
 
 ## Cutting a release of tailwindcss-ruby
 
-- bump the version
+- if it's just bumping the upstream:
+  - [ ] follow the steps above
+  - [ ] when the PR is green, merge the PR
+  - [ ] create a git tag (after updating local `main`)
+- else if the gem is being changed in some other way:
   - [ ] update `lib/tailwindcss/ruby/version.rb`
   - [ ] update `CHANGELOG.md`
-  - [ ] commit and create a git tag
+  - [ ] `git commit`
+  - [ ] `git tag`
 - build the native gems:
-  - [ ] `bundle exec rake clobber` if needed to clean up possibly-old tailwindcss executables
+  - [ ] `bundle exec rake clobber` (if needed to clean up old tailwindcss executables)
   - [ ] `bundle exec rake package`
-- push
+- push source and gems:
   - [ ] `for g in pkg/*.gem ; do gem push $g ; done`
   - [ ] `git push && git push --tags`
 - announce
