+	Short: "Stake a node in the network",
+	Long: `Stake a node in the network, promoting it to a servicer or a validator.
+
+The command takes the following parameters.
+
+  OperatorPublicKey Public key to use as the node's operator account
+  OutputAddress     Address to use as the node's output account
+  SignerAddress     Address to sign the transaction
+  Stake             Amount to stake in uPOKT
+  ChainIDs          Comma-separated chain IDs to host on the node
+  ServiceURL        Relay endpoint of the node.  Must include the port number.
+  RewardDelegators  Addresses to share rewards
+  NetworkID         Network ID to submit a transaction to e.g. mainnet or testnet
+  Fee               Transaction fee in uPOKT
+  Memo              Optional. Text to include in the transaction.  No functional effect.
