+# Homebrew Packaging Notes
+
+## Prep PR
+
+* Edit
+  `/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/s/sugarjar.rb`
+  modifying the version and the sha. See [previous
+  example](https://github.com/Homebrew/homebrew-core/pull/162477)

+
+## Test
+
+Do a install from source:
+
+```shell
+HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source sugarjar
+```
+
+Then test:
+
+```shell
+brew test sugarjar
+brew audit --strict sugarjar
+```
+
+## Make PR
+
+The real upstream has to be called `origin` in Homebrew, so push to our

+git push jaymzh <branchname>
+```
+
+And make the PR from the webUI.
