+:description: Use variables to create dynamic dashboards.
+
+By configuring variables for a dashboard, you can create dashboards with dynamic widgets. Variables enable the reuse of a single dashboard definition for different use-cases. 
+
+== Viewing dashboard variables
+In the top navigation bar, use the dropdown menu next to the "Save..." button, and click "Edit dashboard variables".
+
+// TODO STAC-22767 Add a screenshot
+
+=== Built-in variables
+There are variables that are built-in to {stackstate-product-name}. The names of these variables are reserved, and you cannot give your own variables the same names.
+
+To view all built-in variables, click the accordion titled "SUSE Observability PromQL variables".
+
+== Adding a new variable
+
+. Open the "Edit dashboard variables" drawer. 
+. Click the "Add variable" button to open a second drawer where you can configure the new variable.
+
+// TODO STAC-22767 Add a screenshot
+
+The configuration fields for a variable are as follows:
+
+|===
+| Field name | Description
+
+| Name
+| The name identifier of the variable. This is the name that you can <<using-variables, use in compatible fields>>.
+
+| Display label
+| A friendly name for the variable that is shown on the dashboard when <<selecting-variables, selecting the variable>>. This helps you identify the variable.
+
+| Description
+| A description to understand the purpose for the variable. This description is shown in the "Edit dashboard variables" drawer.
+
+| Type
+| The type of the variable.
+|===
+
+== Variable types
+=== Text variable
+
+A text variable contains simple text. You can set an initial value and make the variable read-only.
+
+=== List variable
+
+A list variable has possible values which are defined by the "Source" field. Each source type provides additional fields which allow you to narrow down the possible values for the variable.
+
+|===
+| Source type | Source fields
+
+| Metric label names
+| Enter zero or more series selectors to refine which metric label names are present.
+
+| Metric label values
+| Enter a metric label name, and zero or more series selectors to refine which metric label values are present.
+
+| Metric PromQL
+| Enter a custom PromQL query, and a label name. The resulting possible values are the values for the given label name.
+
+| Static list
+| Enter one or more label and value pairs to construct a static list of possible values.
+|===
+
+As you change the source type and their related fields, the preview on the right-hand-side of the drawer will update with the new possible values.
+
+
+==== Common list variable settings
+
+All list variable sources also have the following common settings:
+
+|===
+| Field name | Description
+
+| Sort
+| Sort the values in the list. For example, alphabetically or numerically.
+
+| Allow multiple values
+| Allow users to select more than one value at a time.
+
+| Enable "Include Everything" option
+| Adds an option to the list to select all values. You can specify a custom value for this option, or let it be automatically generated.
+|===
+
+
+== Using variables [[using-variables]]
+Once a variable is defined, it can be used to populate various fields in the dashboard:
+
+* Other variables
+* Widget queries, links
+* TODO STAC-22767 - list other places?
+
+To use a variable in a compatible field, use the variable name preceded by a `$` (for example, `$my_variable`). The value of the variable is interpolated.
+
+== Selecting variables [[selecting-variables]]
+Variables are listed towards the top of the dashboard, next to the time range selector. Only the first few variables are shown. To see the rest of the variables, use the "More" dropdown.
+
+Click a variable to open its selector, and select the values you wish to show on the dashboard.
+
+As you select different values, the widgets using the variable will react to the changes.

+:description: Visualize data from your resources with various widgets.
+
+Widgets are the building blocks of your dashboard. They visualize data, usually from one or many Kubernetes resources. Widgets can also show static text information to viewers of the dashboard.
+
+== Adding a new widget
+
+You can add a new widget in either of the two ways:
+
+* Click the *Add Widget* button in the top right of a dashboard.
+
+* On an empty dashboard, click the *Add Widget* section in the middle of the screen. A drawer opens where you can configure the new widget.
+
+
+
+// TODO STAC=-22767 Add a screenshot
+
+== Adding an existing widget
+
+When viewing an individual component in {stackstate-product-name}, you can add charts directly to a dashboard by using the "more actions" menu and selecting "Add to dashboard".
+
+// TODO STAC-22767 Add a screenshot
+
+This is also available for any pinned items.
+
+// TODO STAC-22767 Add a screenshot showing add all items to dashboard from pinned items drawer.
+
+The resulting widget in the dashboard has a link to the resource it was added from.
+
+== Configuring a widget
+
+Each widget has a number of configuration options. Some are common to all widgets, others are based on the widget type.
+
+=== Common widget fields
+
+|===
+| Field name | Description
+
+| Name
+| A short, descriptive name shown in the header of the widget.
+
+| Description
+| Additional details shown in the header of the widget behind a tooltip.
+
+| Type
+| The <<types,type of visualization>>.
+|===
+
+In addition to these fields, there are some common tabs to all widgets: 
+
+|===
+| Tab name | Description
+
+| Links
+| Related resource links, shown underneath the name of the widget. The first link is always displayed. Other links are available in a dropdown menu.
+
+| YAML
+| The raw YAML configuration for the widget, which can be viewed and edited.
+|===
+
+
+=== Queries tab
+
+Widget types intended to show data from resources will have a *Queries* tab. You can add one or more PromQL queries to retrieve the data for the widget.
+
+
+=== Types [[types]]
+
+==== TimeSeriesChart
+
+The `TimeSeriesChart` visualizes time series data in a line chart. Each query in the widget configuration produces a line on the chart.
+
+// TODO STAC-22767 Add a screenshot
+
+You can configure the following settings:
+
+* *Legend* - The position and mode of the legend.
+* **Visual** - Connect null values to create a continuous line.
+* **Y Axis** - The unit, label and min/max values for the Y-axis.
+* **Thresholds** - Add horizontal lines to the chart to mark important value thresholds.
+
+==== BarChart
+
+The `BarChart` visualizes time series data in a bar chart. It has the same settings for legend, Y-axis and thresholds as the `TimeSeriesChart`.
+
+// TODO STAC-22767 Add a screenshot
+
+==== StatChart
+
+The `StatChart` shows a sparkline chart and a single value that is easy to read at a glance. Thresholds can be configured to change the color of the text based on the value.
+
+// TODO STAC-22767 Add a screenshot
+
+You can configure the following settings:
+
+* **Sparkline** - Show or hide the sparkline chart.
+* **Unit** - The unit of the value.
+* **Decimals** - The number of decimals to show.
+* **Calculation** - The method used to calculate the value from the time series data.
+
+==== GaugeChart
+
+The `GaugeChart` displays a gauge with a value in the middle. The color of the gauge and the text change when the value crosses a threshold.
+
+// TODO STAC-22767 Add a screenshot
+
+You can configure the following settings:
+
+* **Unit** - The unit of the value.
+* **Decimals** - The number of decimals to show.
+* **Max** - The maximum value of the gauge.
+* **Calculation** - The method used to calculate the value from the time series data.
+
+==== Markdown
+
+The `Markdown` widget displays markdown text. This can be used to add explanations or other information to your dashboard.

+:description: Create and manage dashboards to visualize data from your resources.
+
+A dashboard visualizes data from your resources and can be created and customized to suit your needs. A dashboard can include resources from distinct parts of your IT environment.
+
+== Create a new dashboard
+
+To create a new dashboard:
+
+. In the main menu, click **Dashboards**.
+. Click the **Add new dashboard** button in the top-right.
+. Fill in the **Name** and **Description**.
+. (Optional) Select **Public** to make the dashboard visible to all users.
+. (Optional) Select **Starred** to add the dashboard to the main menu for quick access.
+. Click **Create dashboard**.
+
+You will be navigated to the new empty dashboard.
+
+// TODO STAC-22767 Add screenshots of the process?
+
+== Dashboard properties
+
+Once on a dashboard, you can edit the properties of a dashboard by using the dropdown menu next to the *Save...* button in the top navigation bar and selecting **Edit dashboard properties**. From here, you can update the name and description, and whether the dashboard is public or starred.
+
+=== Public dashboards
+By default, only you can see your dashboards. Making a dashboard public makes it visible to all users. Public dashbords are viewable but not editable by others.
+
+=== Starred dashboards
+Starring a dashboard makes it appear mroe prominently in the main menu, and when adding widgets from other pages. Star a dashboard when you want quick access to it.
+
+Starred dashboards are scoped to your user. Other users have their own starred dashboards.
+
+You can also star or unstar a dashboard wherever you see the star icon next to a dashboard's name.
+
+== Dashboard settings
+
+Dashboard settings give you control over whether the time range, data refresh interval and variables are saved in the dashboard or customizable by viewers. Click the cog icon in the top right of a dashboard to open the dashboard settings.
+
+When you enable one of the checkboxes under the "Saving..." heading, for example the time range, the dashboard will be fixed to the chosen time range once it has been saved. When it is disabled, the time range can be chosen by the viewer of the dashboard; the change is reflected in the URL, so the link can be shared with other people, who can then view the dashboard with the same time range.
