+          <h3>Configure availability</h3>
+          Availability is the status of your application determined by availability levels set on a
+          time series metric. To create an availability level, you must configure the following:
+          <ul>
+            <li>color: The color of the availability badge on the home page</li>
+            <li>name: The text in the availability badge on the home page</li>
+            <li>expression: Comparison operator to determine the availability</li>
+            <li>value: Value to use when calculating availability</li>
+          </ul>
+          <h3>Configuring availability</h3>
+          By default, Application analytics shows results from the last 24 hours of your data. To
+          see data from a different timeframe, use the date and time selector.
+          <h3>Time series metric</h3>A time series metric is any visualization that has a query that
+          spans over a timestamp and is a bar/line chart. You can use the PPL language to define
+          arbitrary conditions on your logs to create a visualization over time.
+          <h4>Example</h4>
+          <EuiCodeBlock>
+            {'source = <index_name> | ... | ... | stats ... by span(<timestamp_field>, 1h)'}
+          </EuiCodeBlock>
+          You can then choose <strong>Bar</strong> or <strong>Line</strong> in visualization
+          configurations to create a time series metric.
+        </EuiText>
