This will cause the `gen-addon` script to run incorrectly and leave your changes in a broken state. To fix this, uncompress the zip file and open the top-level directory, so you are viewing a collection of files and folders such as `_downloads`, `_images`, `objects.inv`, and others. Select all these files and folders and compress into a new zip file, which you will rename (see step 5 below) and upload (step 6).
 
 4. On some operating systems, the downloaded zip file will be auto-expanded rather than staying a zip file. If this happens, compress it back to a zip file. On macOS, secondary-click on the folder in Finder and use the "Compress" option.
 5. Rename the downloaded zip file with its minor-version number. For example, for the release `0.45.2`, rename `html_docs.zip` to `0.45.zip`. For release candidates (rc), use a value like `2.3-rc.zip`.
