-Grafana metrics can be embedded in [GitLab Flavored Markdown](../../user/markdown.md).
+Grafana panels can be embedded in [GitLab Flavored Markdown](../../user/markdown.md). You can
+embed Grafana panels using either:
 
-## Embedding charts via Grafana rendered images
+- [Grafana-rendered images](#use-grafana-rendered-images).
+- [Grafana API](#use-integration-with-grafana-api).
 
-You can embed live [Grafana](https://docs.gitlab.com/omnibus/settings/grafana.html)
-charts in issues as a
-[direct linked rendered image](https://grafana.com/docs/grafana/latest/reference/share_panel/#direct-link-rendered-image). Your Grafana instance must be available to the
-target user, either as a public dashboard or on the same network. The

+1. Go to the dashboard containing the panel in Grafana.
+1. From the panel's menu, select **Share**.
+1. Select the **Direct link rendered image** button, which provides the link.

+### Set up Grafana integration
 
-## Setting up the Grafana integration
+To set up the Grafana API in Grafana:
 
 1. In Grafana, [generate an Admin-level API Token](https://grafana.com/docs/grafana/latest/http_api/auth/#create-api-token).
-1. In your GitLab project, navigate to **Settings > Operations > Grafana Authentication**.
+1. In your GitLab project, go to **Settings > Operations** and expand the **Grafana authentication**
+   section.
 1. To enable the integration, check the **Active** checkbox.
 1. For **Grafana URL**, enter the base URL of the Grafana instance.
-1. For **API Token**, enter the Admin API Token you just generated.
+1. For **API Token**, enter the Admin API token you just generated.
 1. Click **Save Changes**.
 
-## Generating a link to a chart
+### Generate a link to a panel
+
+To generate a link to a panel:
 
-1. In Grafana, navigate to the dashboard you wish to embed a panel from.
-   ![Grafana Metric Panel](img/grafana_panel_v12_5.png)
-1. In the upper-left corner of the page, select a specific value for each variable
-   required for the queries in the chart.
-   ![Select Query Variables](img/select_query_variables_v12_5.png)
-1. In Grafana, click on a panel's title, then click **Share** to open the panel's
-   sharing dialog to the **Link** tab. If you click the _dashboard's_ share panel
-   instead, GitLab attempts to embed the first supported panel on the dashboard (if available).

 1. If your Prometheus queries use Grafana's custom template variables, ensure the
-   **Template variables** option is toggled to **On**. Of Grafana global template
-   variables, only `$__interval`, `$__from`, and `$__to` are supported.
-1. Toggle **On** the **Current time range** option to specify the time range of
-   the chart. Otherwise, the default range is the last 8 hours.
-   ![Grafana Sharing Dialog](img/grafana_sharing_dialog_v12_5.png)
-1. Click **Copy** to copy the URL to the clipboard.
-1. In GitLab, paste the URL into a Markdown field and save. The chart takes a few
-   moments to render.
