 **NOTE:**
 
 **If no any containers/images, will have problem when execute the front commands.**
 
 **Also, make sure current user is in `sudoers` list. Else need add `sudo` in the front of each commands.**

+-----------------------
+
+### Difference between `stop` and `kill`
+- `docker stop`: Stop a running container (send SIGTERM, and then SIGKILL after grace period)
+   The main process inside the container will receive SIGTERM, and after a grace period, SIGKILL
+   
+- `docker kill`: Kill a running container (send SIGKILL, or specified signal) 
+   The main process inside the container will be sent SIGKILL, or any signal specified with option --signal.
+
+Means, *"kill"* will stop container immediately, *"stop"* before stop, still have time to clean up, save state,finish any currently-executing requests, etc.
