+Usage: vault renew [options] id [increment]
+
+  Renew the lease on a secret, extending the time that it can be used
+  before it is revoked by Vault.
+
+  Every secret in Vault has a lease associated with it. If the user of
+  the secret wants to use it longer than the lease, then it must be
+  renewed. Renewing the lease will not change the contents of the secret.
+
+  To renew a secret, run this command with the lease ID returned when it
+  was read. Optionally, request a specific increment in seconds. Vault may
+  is not required to honor this request.
+
+General Options:
+
+  -address=TODO           The address of the Vault server.
+
+  -ca-cert=path           Path to a PEM encoded CA cert file to use to
+                          verify the Vault server SSL certificate.
+
+  -ca-path=path           Path to a directory of PEM encoded CA cert files
+                          to verify the Vault server SSL certificate. If both
+                          -ca-cert and -ca-path are specified, -ca-path is used.
+
+  -insecure               Do not verify TLS certificate. This is highly
+                          not recommended. This is especially not recommended
+                          for unsealing a vault.
+
+Renew Options:
+
+  -format=table           The format for output. By default it is a whitespace-
+                          delimited table. This can also be json.
