+## Docker ps
+
+`docker ps` list containers on your system.  
+A simple `docker ps` will only list all *running* containers, whereas for example a `docker ps -a` will list you all containers (including exited).  
+It will provide you with crucial informations regarding your containers like the `CONTAINER ID`, which is especially useful for accessing your container(s).  
+
+```bash
+CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                   PORTS               NAMES
