+Usage: $(basename "$0") [OPTIONS]
+
+Options:
+  --chain <name>    Specify network: 'sepolia' or 'mordor'. If omitted, checks both.
+  --output <dir>    Base directory to save results. Creates a subfolder with Unix Timestamp.
+  --rpcs <urls>      Comma-separated list of custom RPC endpoints.
+                    Disables default Sepolia/Mordor lists.
+  --help            Show this help message.
+
+Example:
+  $0 --chain sepolia --output ./logs
