 ## Description
 
 A data pipeline, in general, is a series of data processing
 [stages](/doc/command-reference/run) (for example console commands that take an
 input and produce an <abbr>output</abbr>). A pipeline may produce intermediate
-data, and has a final result. Machine learning (ML) pipelines typically start a

+Machine learning (ML) pipelines typically start a with large raw datasets,
+include intermediate featurization and training stages, and produce a final
+model, as well as accuracy [metrics](/doc/command-reference/metrics).
 
 In DVC, pipeline stages and commands, their data I/O, interdependencies, and
-results (intermediate or final) are specified with `dvc add` and `dvc run`,
-among other commands. This allows DVC to restore one or more pipelines of stages
-interconnected by their dependencies and outputs later. (See `dvc repro`.)
+results (intermediate or final) are specified in `dvc.yaml`, which can be
+written manually or built using the helper command `dvc run`. This allows DVC to
+restore one or more pipelines later (see `dvc repro`).
 
 > DVC builds a dependency graph
 > ([DAG](https://en.wikipedia.org/wiki/Directed_acyclic_graph)) to do this.

 ## Options
 
+- `--full` - show full DAG that the `target` stage belongs too, instead of
+  showing only its ancestors.
+
 - `--dot` - show DAG in
   [DOT](<https://en.wikipedia.org/wiki/DOT_(graph_description_language)>)
   format. It can be passed to third party visualization utilities.
 
-- `--full` - show full DAG that the `target` belongs too, instead of showing the
-  part that consists only of the target ancestors.
-
 - `-h`, `--help` - prints the usage/help message, and exit.
 
 - `-q`, `--quiet` - do not write anything to standard output. Exit with 0 if no
