+By default `rad clone` should add a seeding policy with the `followed` scope:
+
+```
+$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
+✓ Seeding policy updated for rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji with scope 'followed'
+✓ Creating checkout in ./heartwood..
+✓ Repository successfully cloned under [..]/heartwood/

+│ 0 issues · 0 patches               │

+Run `cd ./heartwood` to go to the repository directory.
+$ rad seed

+╰───────────────────────────────────────────────────────────────────╯
+$ rm -rf heartwood
+```
+
+Specifying a different scope explicitly should update the policy:
+
+```
+$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --scope all
+✓ Seeding policy updated for rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji with scope 'all'
+✓ Creating checkout in ./heartwood..
+✓ Repository successfully cloned under [..]/heartwood/

+Run `cd ./heartwood` to go to the repository directory.

+╰────────────────────────────────────────────────────────────────╯
+$ rm -rf heartwood
+```
+
+Running `rad clone` again without an explicit scope parameter should not change the existing policy:
+
+```
+$ rad clone rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
+✓ Creating checkout in ./heartwood..
+✓ Repository successfully cloned under [..]/heartwood/
