+# Expo Integration
+
+## Overview
+
+With the Datadog [Expo integration][1], you can spend less time triaging issues and more time releasing new features by:
+
+- Debugging the root cause of slow performance issues and application crashes in third-party libraries, network requests, or large media files
+- Improving application responsiveness, setting up service level indicators (SLIs), and diagnosing issues with out-of-the-box dashboards, real-time metrics, and deobfuscated crash reports
+- Intelligently grouping high-volume application errors into a manageable set of unique issues
+
+Correlate the impact of the user experience on your business by:
+
+- Analyzing critical mobile user experience data such as screen engagement by demographics, version releases, or any custom attributes, to reach your business KPIs
+- Automatically correlating every user journey with a timeline of session events and attributes including ID, cellular activity, referral URL, and more
+- Understanding user behavior trends with customizable analytics and geographical maps
+
+Monitor the end-to-end health of your Expo application by:
+
+- Pivoting from your user experience data to backend traces, runtime metrics, and logs for the complete context when investigating issues
+- Debugging crashes faster by unifying client-side and server-side metrics, traces, and logs
+- Unifying full-stack monitoring in a single platform for frontend and backend teams
+
+## Setup
+
+### Collect RUM events
+
+To start collecting Real User Monitoring events from your application, see [Expo Monitoring][2].
+
+### Collect traces
+
+Your Expo application automatically sends traces to Datadog.
+
+### Collect logs
+
+To start forwarding your Expo application's logs to Datadog, see [Expo Log Collection][3].
+
+## Data Collected
+
+### Metrics
+
+The Expo integration does not include any metrics. To generate custom metrics from your RUM application, see [Generate Metrics][4].
+
+### Events
+
+For more information about events and attributes, see [RUM Expo Monitoring][5].
+
+### Service Checks
+
+The Expo integration does not include any service checks.
+
+## Troubleshooting
