+=== View and filter detection alerts
+The Detections page offers a variety of ways for you to organize and triage detection alerts as you investigate suspicious events. You can:
 
 * Filter for a specific rule in the KQL bar (for example,
 `signal.rule.name :"SSH (Secure Shell) from the Internet"`).
-* View detection alerts in the *Rule details* page (click
-*Manage detection rules* -> rule name in the *All rules* table).
 
 NOTE: KQL autocomplete for `.siem-signals-*` indices is available on the
 *Detections* and *Rule details* pages, and in Timeline when either `All` or
 `Detection alerts` is selected.
 
-TIP: Use the icons in the upper left corner of the Alerts table to customize
-displayed columns and row renderers, and view the table in full screen mode.
+* Use the date and time filter to select a time range that you’re interested in exploring. By default, this filter is set to search through the last 24 hours.
+* View detection alerts generated by a specific rule. To do this, click
+*Manage detection rules* and then click on a rule name in the All rules table. A new page showing the detailed view of the rule displays and alert details are stored in the Alerts table beneath the Detection alert trend histogram.
+* Use the *Stack by* dropdown in the Detection alert trend histogram to select specific parameters for which to visualize the individual counts. For example, if you choose to stack by `signal.rule.name`, the histogram will display the total counts by alert name.
+* Augment the results shown in the Alerts table to include alerts from building blocks or only show alerts from indicator match rules. By default, building block alerts are excluded from the Alerts table. Opting to include them expands the results and displays building block alerts alongside regular detection alerts.
+
+NOTE: When updating alert results to also include building block alerts, the Security app searches the `.siem-signals-<Kibana space>` index for the `signal.rule.building_block_type` field. When looking for alerts created from indicator match rules, the app searches the same index for the `signal.rule.threat_mapping` field.

+Click the *Customize Event Renderers* icon to enable event renderers within the Alerts table. When enabled, event renderers show relevant details that provide more context to the event. For example, if you enable the *Flow* Event Renderer, the Alerts table shows relevant details describing the flow of the data between a source and destination. These details could include hosts, ports, protocol, direction, duration, amount transferred, process, and geographic location.

+
+The Alert details flyout appears and offers several options for viewing alert details:
+
+* *Summary*: Offers an aggregated view of alert details. Alerts that have been enriched with `threat.indicator` data also display the *threat summary* section, which is an additional section located beneath the alert summary. In the *threat summary* section, you can view mapped data for the following `threat.indicator` subfields:
+** `matched.field`
+** `matched.type`
+** `source (threat.indicator.provider)`
+** `first_seen`
+** `last_seen`
+
+NOTE: If an alert has more than one threat, `threat.indicator` data is still aggregated under the *threat summary* section, but parsed out in the *Threat Intel* tab.
+
+* *Threat Intel*: Shows the number of matched intelligence sources and displays threats individually. Threats are organized by timestamp (the most recent threat alert is shown at the top and the oldest is at the bottom) and the available `threat.indicator` and `source.event` data is portrayed for each threat. If the alert has not been enriched with threat data the *Threat Intel* tab displays the message `No Threat Intel Enrichment Found` and provides a link to Threat Intel module documentation.
+* *Table*: Shows the alert details in table format. Alert details are organized into field value pairs.
+* *JSON View*: Shows the alert details in JSON format.
