+
+## NAME
+podman-remote - A remote CLI for Podman: A Simple management tool for pods, containers and images.
+
+## SYNOPSIS
+**podman-remote** [*options*] *command*
+
+## DESCRIPTION
+Podman (Pod Manager) is a fully featured container engine that is a simple daemonless tool.
+Podman provides a Docker-CLI comparable command line that eases the transition from other
+container engines and allows the management of pods, containers and images. Simply put: `alias docker=podman`.
+Most Podman commands can be run as a regular user, without requiring additional
+privileges.
+
+Podman uses Buildah(1) internally to create container images. Both tools share image
+(not container) storage, hence each can use or manipulate images (but not containers)
+created by the other.
+
+Podman-remote provides a local client interacting with a Podman backend node through a varlink ssh connection. In this context, a Podman node is a Linux system with Podman installed on it and the varlink service activated. Credentials for this session can be passed in using flags, enviroment variables, or in `podman-remote.conf`
+
+**podman [GLOBAL OPTIONS]**
+
+## GLOBAL OPTIONS
+
+**--connection**=*name*
+
+Remote connection name
+
+**--help**, **-h**
+
+Print usage statement
+
+**--log-level**=*level*
+
+Log messages above specified level: debug, info, warn, error (default), fatal or panic
+
+**--remote-config-path**=*path*
+
+Alternate path for configuration file
+
+**--remote-host**=*ip*
+
+Remote host IP
+
+**--syslog**
+
+Output logging information to syslog as well as the console
+
+**--username**=*string*
+
+Username on the remote host (defaults to current username)
+
+**--version**
+
+Print the version
+
+## Exit Status
+
+The exit code from `podman` gives information about why the container
+failed to run or why it exited. When `podman` commands exit with a non-zero code,
+the exit codes follow the `chroot` standard, see below:
+
+**_125_** if the error is with podman **_itself_**
+
+ $ podman run --foo busybox; echo $?
+ Error: unknown flag: --foo
+ 125
+
+**_126_** if executing a **_contained command_** and the **_command_** cannot be invoked
+
+ $ podman run busybox /etc; echo $?
+ Error: container_linux.go:346: starting container process caused "exec: \"/etc\": permission denied": OCI runtime error
+ 126
+
+**_127_** if executing a **_contained command_** and the **_command_** cannot be found
+ $ podman run busybox foo; echo $?
+ Error: container_linux.go:346: starting container process caused "exec: \"foo\": executable file not found in $PATH": OCI runtime error
+ 127
+
+**_Exit code_** of **_contained command_** otherwise
+
+ $ podman run busybox /bin/sh -c 'exit 3'
+ # 3
+
