 For example:
 
-    sudo docker run -t -i -v /var/logs:/var/host_logs:ro ubuntu bash
+    # Usage:
+    # sudo docker run [OPTIONS] -v /(dir. on host):/(dir. in container):(Read-Write or Read-Only) [ARG..]
+    # Example:
+    sudo docker run -i -t -v /var/log:/logs_from_host:ro ubuntu bash
 
-The command above mounts the host directory `/var/logs`
-into the container with read only permissions as
-`/var/host_logs`.
