 # CLI Reference
+
+The Reth node is operated via the CLI by running the `reth node` command. To stop it, press `ctrl-c`. You may need to wait a bit as Reth tears down existing p2p connections or other cleanup tasks.
+
+However, Reth has more commands than that:
+
+```bash
+reth --help
+```
+
+Some of the most useful commands as a node developer are:
+* [`reth node`](./node.md): Starts the Reth node's components, including the JSON-RPC. 
+* [`reth db`](./db.md): Administrative TUI to the key-value store
+* [`reth p2p`](./p2p.md): P2P-related utilities
+* [`reth stage`](./stage.md): Runs a stage in isolation. Useful for testing and benchmarking.
+* [`reth drop-stage`](./drop-stage.md): Drops all the tables associated with a stage. Useful for resetting state.
+* [`reth dump-stage`](./dump-stage.md): Dumps all the tables associated with a stage to a new database. Useful for creating snapshots
+
+See below for the full list of commands.
