+# Docker
+
+
+Docker stores images at /var/lib/docker/ (managed by the Docker daemon). You don't interact with it directly — Docker
+   handles the layers.                                                                                                 
+                                                                                                                       
+  Your cheat sheet:

+  The aipass-test image (~260MB) stays until you docker rmi aipass-test. The container stays until you docker rm it.
+  Both survive reboots.
