+## NAME
+podman\-system\-connection\-add - Record destination for the Podman service
+
+## SYNOPSIS
+**podman system connection add** [*options*] *name* *destination*
+
+## DESCRIPTION
+Record ssh destination for remote podman service(s). The ssh destination is given as one of:
+ - [user@]hostname[:port]
+ - ssh://[user@]hostname[:port]
+
+The user will be prompted for the remote ssh login password or key file pass phrase as required. The `ssh-agent` is supported if it is running.
+
+## OPTIONS
+
+**-d**, **--default**=*false*
+
+Make the new destination the default for this user.
+
+**--identity**=*path*
+
+Path to ssh identity file. If the identity file has been encrypted, Podman prompts the user for the passphrase.
+If no identity file is provided and no user is given, Podman defaults to the user running the podman command.
+Podman prompts for the login password on the remote server.
+
+**-p**, **--port**=*port*
+
+Port for ssh destination. The default value is `22`.
+
+**--socket-path**=*path*
+
+Path to the Podman service unix domain socket on the ssh destination host
+
+## EXAMPLE
+```
+$ podman system connection add QA podman.example.com
+
+$ podman system connection add --identity ~/.ssh/dev_rsa production ssh://root@server.example.com:2222
+```
