 to reflect the structure of the Compose file itself. Top-level keys that define
 a section in the configuration file such as `build`, `deploy`, `depends_on`,
 `networks`, and so on, are listed with the options that support them as
-sub-topics. This maps to the `<key>: <option>: <value>` indent structure of the Compose file.

-Example snip-its of how to define particular options are included on this
-reference page, but we suggest also taking a look at some samples that include
-full Compose files. A good place to start are the [sample
-applications](samples.md#sample-applications) in [Docker
-Labs](https://github.com/docker/labs/) and the [voting app sample
-walk-through](/engine/getstarted-voting-app/index.md).
+The best way to quickly grok the layout and syntax of a Compose file is to look
+at files for [sample applications](samples.md). A good place to start is the
+version 3 Compose stack file we use for the voting app sample to illustrate
+multi-container apps, service definitions, swarm mode, the `deploy` key, and the
+`docker stack deploy` command. Click to show/hide the example file below. This
+file is fully explained in the [voting app sample
