+### Get the latest released zip URL
+
+If you would like to get the latest release zip URL, which can be used in the methods mentioned above, you can use the following helper function to do so:
+
+`getLatestReleaseZipUrl( owner, repository, getPrerelease, perPage )`
+
+This will return a string with the latest release URL. Optionally, you can use the `getPrerelease` boolean flag, which defaults to false, on whether or not to get a prerelease instead. The `perPage` flag can be used to return more results when getting the list of releases. The default value is 3.
