+# Signer registration utility
+
+This utility can be used to register an op-enclave signer key with the
+[SystemConfigGlobal](../contracts/src/SystemConfigGlobal.sol) contract.
+
+## Installation
+
+```
+go install github.com/base-org/op-enclave/register-signer
+```
+
+## Usage
+
+Query an AWS Nitro attestation from op-enclave server:
+```bash
+curl -d '{"id":0,"jsonrpc":"2.0","method":"enclave_signerAttestation"}' -H "Content-Type: application/json" http://op-enclave:7333
+```
+
+```
+Usage of register-signer:
+  -attestation string
+    	attestation hex
+  -deployment string
+    	deployment file (default "deployments/84532-deploy.json")
+  -private-key string
+    	private key
+  -rpc string
+    	rpc url (default "https://sepolia.base.org")
+```
