-Select one or more experiments to visualize them in the
-[`Plots Dashboard`](command:dvc.showPlots). This is the extension's equivalent
-of the `dvc plots show` and `dvc plots diff` commands.
+Select one or more experiments to visualize in the
+[**Plots Dashboard**](command:dvc.showPlots). Use
+[`DVC: Show Plots`](command:workbench.action.quickOpen?%22>DVC:%20Show%20Plots%22)
+from the command palette to open it.
 
-💡 If you don't have any DVC
-[plots](https://dvc.org/doc/command-reference/plots) in the project, start
-writing data points into JSON, YAML, CSV or TSV or saving plots as images
-(`.png`, etc) (check the [DVCLive](https://dvc.org/doc/dvclive) helper library
-if you use Python):
+[`dvc plots show`]: https://dvc.org/doc/command-reference/plots/show
+[`dvc plots diff`]: https://dvc.org/doc/command-reference/plots/diff
+
+💡 To add [DVC plots] to the project, start writing data series into JSON, YAML,
+CSV, or TSV files; or save your own plot images (`.png`, etc.). If you're using
+Python, the [DVCLive] helper library can save plots data for you!

-Use `DVC: Show Plots` from the
-[Command Palette](command:workbench.action.quickOpen?%22>DVC:%20Show%20Plots%22)
-to open up the plots dashboard. The extension will display the following
-sections for selected experiments, that correspond to the different
-[types of plots](https://dvc.org/doc/command-reference/plots#supported-file-formats)
-supported by DVC:
+[dvc plots]: https://dvc.org/doc/start/experiments/visualization
+[dvclive]: https://dvc.org/doc/dvclive
+
+These are the types of plots that can be displayed (for the selected
+experiments):
 
 <p align="center">
   <img src="images/plots-data-series.png"
        alt="Plots: Data Series" />
 </p>
 
-`Data Series`. JSON, YAML, CSV or TSV files visualized using the predefined
-(e.g. confusion matrix, linear) or custom (Vega-lite) templates.
+**Data Series** are JSON, YAML, CSV, or TSV files visualized using [plot
+templates], which may be predefined (e.g. confusion matrix, linear) or custom
+([Vega-lite] files)
+
+[plot templates]:

 <p align="center">
   <img src="images/plots-images.png"
        alt="Plots: Images" />
 </p>
 
-`Images`. Any image file (e,g `.png`) can be visualized as a plot. They will be
-rendered side by side in the table.
-
 <p align="center">
   <img src="images/plots-trends.png"
        alt="Plots: Trends" />
 </p>
 
-`Trends`. Linear plots based on data from the experiments table if you use
-[checkpoints](https://dvc.org/doc/user-guide/experiment-management/checkpoints).
-
-The plots dashboard can be configured and accessed using using the `Plots` and
-`Experiments` views:
+**Images** (e.g. `.jpg` or `.svg` files) can be visualized as well. They will be
+rendered side by side for the selected experiments.

+Real-time **Trends** based on scalar [metrics] from the **Experiments Table**
