 # Agenda
 
-* Build (build)
+* Definitions
+* Architecture
 * Start/Stop container (ps, start, stop)
 * Getting a shell (run vs exec)
+* Dockerfile
 * Analyzing an image (dive, docker layers)
 * Shrinking an image (compression, discuss the trade offs of having more v. less layers)
-* Sharing an image (push, pull, authn)
