 ### Updating the Repository

+1. Run `git checkout -b ...` to create a new branch.  Typical practice is to create a new branch for a major version, such as `v44`, and only merge it back to `main` upon release.
 2. Run `git status` to check whether there are any newly added files/directories such as for new locales, or removed files/directories.  If you see any files or directories named `other…`, stop, because there's a generation problem.
 3. Run `git add cldr-json` to add the entire nested `cldr-json` subdirectory.
-4. Make a pull request (`git commit ...`, `git push`, ...), get it approved, and merge it.
+4. Open a draft pull request for the `v44` branch to be able to track updates to the data in progress.
 
 ### Publishing
 
 1. Run the script `cldr-generate-zip.sh` to generate zipfiles under `dist/`; their names will include `VERSION`, for example: `cldr-44.0.0-ALPHA2-json-full.zip`.
