+- By querying the signer set from the Amplifier contract (this only works if Amplifier contracts have been setup):
+
+```bash
+node sui/deploy-gateway.js
+```
+
+Use `--help` flag to see other setup params that can be overridden.
+
+- For testing convenience, you can use the secp256k1 wallet as the signer set for the gateway.
+
+```bash
+node sui/deploy-gateway.js --signers wallet
+```
+
+- You can also provide a JSON object with a full signer set:
 
 ```bash
-node sui/deploy-gateway.js -e testnet --signers '{"signers": [{"pubkey": "0x020194ead85b350d90472117e6122cf1764d93bf17d6de4b51b03d19afc4d6302b", "weight": 1}], "threshold": 1, "nonce": ""}'
