+# Benchmark Tests
+
+[Synthetics for Mobile](https://docs.datadoghq.com/mobile_app_testing/) runs Benchmark test scenarios to collect metrics of the SDK performances.
+
+
+## CI
+
+CI continuously builds, signs, and uploads a runner application to Synthetics which runs predefined tests.
+
+### Build
+
+Before building the application, make sure the `BenchmarkTests/xcconfigs/Benchmark.local.xcconfig` configuration file is present and contains the `Mobile - Integration Org` client token, RUM application ID, and API Key. These values are sensitive and must be securely stored.
+
+```ini
+CLIENT_TOKEN=
+RUM_APPLICATION_ID=
+API_KEY=
+```
+
+### Sign
+
+To sign the runner application, the certificate and provision profile defined in [Synthetics.xcconfig](xcconfigs/Synthetics.xcconfig) and in [exportOptions.plist](exportOptions.plist) needs to be installed on the build machine. The certificate and profile are sensitive files and must be securely stored. Make sure to update both files when updating the certificate and provisioning profile, otherwise signing fails.
+
+> [!NOTE]
+> Certificate & Provisioning Profile are also available through the [App Store Connect API](https://developer.apple.com/documentation/appstoreconnectapi). But we don't have the tooling in place.
+
+### Upload
+
+The application version (build number) is set to the commit SHA of the current job, and the build is uploaded to Synthetics using the [datadog-ci](https://github.com/DataDog/datadog-ci) CLI. This step expects environment variables to authenticate with the `Mobile - Integration Org`:
+
+```bash
+export DATADOG_API_KEY=
+export DATADOG_APP_KEY=
+export S8S_APPLICATION_ID=
+```
+
+## Development
+
+Each scenario is independent and can be considered as an app within the runner.
+
+### Create a scenario
+
+A scenario must comply with the [`Scenario`](Runner/Scenarios/Scenario.swift) protocol. Upon start, a scenario initializes the SDK, enables features, and returns a root view-controller.
+
+Here is a simple example of a scenario using Logs:
+```swift
+import Foundation
+import UIKit
+
+import DatadogCore
+import DatadogLogs
+
+struct LogsScenario: Scenario {
+
+    func start(info: TestInfo) -> UIViewController {
+
+        Datadog.initialize(
+            with: .benchmark(info: info), // SDK init with the benchmark configuration
+            trackingConsent: .granted
+        )
+
+        Logs.enable()
+
+        return LoggerViewController()
+    }
+}
+```
+
+Add the test to the [`SyntheticScenario`](Runner/Scenarios/Scenario.swift) enumeration so it can be selected, either manually or by setting the `BENCHMARK_SCENARIO` environment variable.
+
+### Synthetics Configuration
