 The server should be up on `localhost:8080`.
 
+The default config file is `config.yaml`.
+You can specify another config file with:
+```sh
+$ cargo run another_config.yaml
+```
+
+You can even run multiple networks at once by giving multiple configuration files:
+```sh
+# Run both the main network (at /) and testnet (at /testnet)
+# For example, register for main network at `localhost:8080/register`,
+# testnet network at `localhost:8080/testnet/register`
+$ cargo run config.yaml testnet.yaml
+```
+In the config file, `url_prefix` field determines the address of the network.
+
+You can clear the database for all networks by running:
+```sh
+$ rm -rf blocks users
+```
+Or you can delete the database for a particular network by removing `blocks/network_name` and `users/network_name`.
