 ## 3. Usage Guide
 
-\[WIP\]
+To start a client node, run:
+```
+snarkos
+```
+
+To start a mining node, run:
+```
+snarkos --is-miner
+```
+
+#### How to guard RPC endpoints
+```
+./target/release/snarkOS --rpc-username <Username> --rpc-password <Password>
+```
+
+#### How to manually connect to a peer on the network
+```
+./target/release/snarkOS --connect "<IP ADDRESS>"
+```
+
+### Interfacing with a running node
+
+By default, snarkOS runs a JSON-RPC server to allow external interfacing with the Aleo network. Additional information can be found [here](aleo/documentation/autogen/testnet/rpc/rpc_server/00_configurations.md)
