 ## Description
 
-command to read a prepared list in advance and connect ssh/scp/sftp the selected host. List file is set in yaml format. When selecting a host, you can filter by keywords. Can execute commands concurrently to multiple hosts. Supported multiple ssh proxy, http/socks5 proxy, x11 forward, and port forwarding.
+This command utility to read a prepared list in advance and connect ssh/scp/sftp the selected host.
+List file is set in yaml format.
+When selecting a host, you can filter by keywords.
+Can execute commands concurrently to multiple hosts.
+
+lssh also has a shell (parallel shell) that connects to multiple hosts at the same time and pipes the execution results of local commands and remote hosts.
+In addition, lsftp also has a shell that can be connected in parallel.
+
+Supported multiple ssh proxy, http/socks5 proxy, x11 forward, and port forwarding.
