+## Description
+
+The `docker top` command shows the processes running inside a container.
+
+On Linux, extra arguments after the container name are passed through to
+`ps`. On Windows, those extra arguments aren't supported.

+## Examples
+
+### Show processes in a container
+
+```console
+$ docker top my-container
+UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
