 ### File Name and Path
 
-The general recommendation is to name this file `.env` and place it the project root on development systems.  This is the expected default for many DMOD management script and tools.  The Git repo is also configured to ignore this path.

+DMOD deploys using several Docker stacks, and the service/worker containers within those stacks require custom Docker images.  These must be built before a deployment can be started.  The [`scripts/control_stack.sh`](./scripts/control_stack.sh) script has subcommands for performing these builds.
 
 The following is usually enough to get started (note that order is important):
 
 ```
-./scripts/control_stack.sh py-sources build
-./scripts/control_stack.sh main build
+./scripts/control_stack.sh py-sources build push
+./scripts/control_stack.sh main build push
 ```
