+It is possible to use the `rad seed` command to specify multiple RIDs at the
+same time, where each repository specified will be fetched (unless `--no-fetch`
+is used):
+
+```
+$ rad seed rad:z3Rry7rpdWuGpfjPYGzdJKQADsoNW rad:z3zTnCfi6cVSZG8eCGn6AMDypgAPm
+✓ Seeding policy updated for rad:z3Rry7rpdWuGpfjPYGzdJKQADsoNW with scope 'all'
+✓ Fetching rad:z3Rry7rpdWuGpfjPYGzdJKQADsoNW from z6Mkt67…v4N1tRk@[..]
