 ## Adding a new package
 
 The `hubcap.py` script which generates PRs for new versions of packages is hosted at https://github.com/dbt-labs/hubcap and runs hourly on Heroku. To add a new package to the hub index, create a PR which adds the package name to [this file](https://github.com/dbt-labs/hubcap/blob/master/hub.json).
+
+## Rename a package
+
+Renaming a package involves two steps:
+1. Redirecting from the old name to the new name
+1. Removing the old name from the hub homepage
+
+To notify users of a new package name, add a `"redirectname"` key to `data/packages/ORG_NAME/OLD_PACKAGE_NAME/index.json`.
+
+To remove an old package name from the hub homepage, add it to [blocklist.json](data/blocklist.json).
+
+See [#1539](https://github.com/dbt-labs/hub.getdbt.com/pull/1539/files) for an example of both steps.
