+### Combining with built-in network profiles
+
+You can also combine the `--volume` flag with built-in network profiles for a
+flexible approach that doesn't require creating a custom profile file. For
+example, to run the `aws-diagram` server with no network access and file system
+write access:
+
+```bash
+thv run --isolate-network --permission-profile none --volume /home/user/aws-diagrams:/tmp/generated-diagrams aws-diagram
+```
+
+This approach is useful when you need simple file system access combined with
+standard network restrictions.

+### Alternative: Using built-in profiles with volume mounts

+You can achieve the same result without creating a custom profile file by using
+the built-in `none` profile and the `--volume` flag:
+
+```bash
+thv run --isolate-network --permission-profile none --volume /home/user/aws-diagrams:/tmp/generated-diagrams aws-diagram
