 # Experiment Management
 
-_New in DVC 2.0_
-
 Data science and ML are iterative processes that require a large number of
 attempts to reach a certain level of a metric. Experimentation is part of the
 development of data features, hyperspace exploration, deep learning
-optimization, etc. DVC helps you codify and manage all of your
-<abbr>experiments</abbr>, supporting these main approaches:
-
-1. Create [experiments](#experiments) that derive from your latest project
-   version without having to track them manually. DVC does that automatically,
-   letting you list and compare them. The best ones can be made persistent, and
-   the rest archived.
-2. Place in-code [checkpoints](#checkpoints-in-source-code) that mark a series
-   of variations, forming a deep experiment. DVC helps you capture them at
-   runtime, and manage them in batches.
-3. Make experiments or checkpoints [persistent](#persistent-experiments) by
-   committing them to your <abbr>repository</abbr>. Or create these versions
-   from scratch like typical project changes.

+## DVC Experiments
+
+_New in DVC 2.0_
+
+The `dvc experiments` features are designed to support these main approaches:
+
+1. Create [experiments] that derive from your latest project version without
+   polluting your Git history. DVC tracks them for you, letting you list and
+   compare them. The best ones can be made persistent, and the rest left as
+   history or cleared.
+1. [Queue] and process series of experiments based on a parameter search or
+   other modifications to your baseline.
+1. Generate [checkpoints] during your code execution to analyze the internal
+   progress of deep experiments. DVC captures them at runtime, and can manage
+   them in batches.
+1. Make experiments [persistent] by committing them to your
+   <abbr>repository</abbr> history.
