Usage: vault help [options] path

  Look up the help for a path.

  All endpoints in Vault from system paths, secret paths, and credential
  providers provide built-in help. This command looks up and outputs that
  help.

General Options:

  -address=addr           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.
