 # Stage
 
 A stage is a single unit of execution in a <abbr>pipeline</abbr> that takes some
-input and produces an output. A stage is defined by its
+input and produces some <abbr>output</abbr>. A stage is defined by its
 <abbr>dependencies</abbr>, its command and its <abbr>outputs</abbr>.
 
-A stage may have multiple dependencies, multiple commands and multiple outputs.
-A stage can also have <abbr>parameter dependencies</abbr> to represent model
-hyperparameters and similar changes during execution. See `dvc run` for defining
-a stage.
+Stages that depend on other stages can be invalidated by the change in their
+dependencies. A stage may have multiple dependencies, multiple commands and
+multiple outputs. A stage can also have <abbr>parameter</abbr> dependencies to
+represent model hyperparameters and similar changes during execution.
 
 A stage may also represent an <abbr>import</abbr> from outside sources.
