+It is possible to use the `rad unseed` command to specify multiple RIDs at the
+same time, where each repository specified will stop being seeded.
+
+Let's say we have multiple local repositories we've initialized:
+
+```
+$ rad ls
+╭───────────────────────────────────────────────────────────────────────────────────────────────────────────╮
+│ Name        RID                                 Visibility   Head      Description                        │
+├───────────────────────────────────────────────────────────────────────────────────────────────────────────┤
+│ heartwood   rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji   public       f2de534   Radicle Heartwood Protocol & Stack │
+│ nixpkgs     rad:zyFFr2iwoTEfNF4jGNZHuoy7odMh    public       f2de534   Home for Nix Packages              │
+╰───────────────────────────────────────────────────────────────────────────────────────────────────────────╯
+```
+
+We could stop seeding them if we didn't want other nodes to fetch them from us:
+
+```
+$ rad unseed rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji rad:zyFFr2iwoTEfNF4jGNZHuoy7odMh
+✓ Seeding policy for rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji removed
+✓ Seeding policy for rad:zyFFr2iwoTEfNF4jGNZHuoy7odMh removed
+```
