+## Share and reuse server configurations
+
+ToolHive allows you to export a server's configuration and run servers using
+previously exported configurations. This is useful for:
+
+- Sharing server setups with team members
+- Creating backups of complex configurations
+- Running identical server instances across different environments
+
+### Export a server configuration
+
+To export a running server's configuration to a file, use the
+[`thv export`](../reference/cli/thv_export.md) command:
+
+```bash
+thv export <server-name> <output-file>
+```
+
+For example, to export the configuration of a running server named "fetch":
+
+```bash
+thv export fetch ./fetch-config.json
+```
+
+This creates a JSON file containing all the server's configuration, including:
+
+- Container image and version
+- Environment variables and secrets references
+- Volume mounts and permissions
+- Network settings
+- Transport configuration
+
+### Run a server from an exported configuration
+
+To run a server using a previously exported configuration, use the
+[`thv run`](../reference/cli/thv_run.md) command with the `--from-config` flag:
+
+```bash
+thv run --from-config <config-file>
+```
+
+For example, to run a server using the exported configuration:
+
+```bash
+thv run --from-config ./fetch-config.json
+```
+
+This creates a new server instance with identical settings to the original. If
+the original server used secrets, you must have the same secrets available in
+your ToolHive secrets store.
+
+:::info
+
+When running from a configuration file, you can still override specific settings
+using command-line flags. For example:
+
+```bash
+thv run --from-config ./fetch-config.json --name custom-fetch --proxy-port 8080
+```
+
+This runs the server with the exported configuration but uses a custom name and
+port.
