 Useful options:
 
 - `--dry-run` prints the planned changes without modifying files.
-- `--delete-stale` removes managed addons that are no longer in the collections.
+- `--keep-stale` preserves managed addons that are no longer in the collections.
 - `--concurrency <number>` sets the number of concurrent downloads (default: `4`).
 - `--max-stalled-retries <number>` limits retries for downloads that stop making progress.
 - `--log-level <filter>` sets the tracing filter and defaults to `info`.
