# [Android Components](../../../README.md) > Browser > Engine-Gecko
[*Engine*](../../concept/engine/README.md) implementation based on [GeckoView](https://wiki.mozilla.org/Mobile/GeckoView).
## Usage
### Setting up the dependency
Use Gradle to download the library from [maven.mozilla.org](https://maven.mozilla.org/) ([Setup repository](../../../README.md#maven-repository)):
```Groovy
implementation "org.mozilla.components:browser-engine-gecko:{latest-version}"
```
### Integration with the Glean SDK
#### Before using this component
Products sending telemetry and using this component *must request* a data-review following [this process](https://wiki.mozilla.org/Firefox/Data_Collection).
The [Glean SDK](../../../components/service/glean/README.md) can be used to collect [Gecko Telemetry](https://firefox-source-docs.mozilla.org/toolkit/components/telemetry/telemetry/index.html).
Applications using both this component and the Glean SDK should setup the Gecko Telemetry delegate
as shown below:
```Kotlin
val builder = GeckoRuntimeSettings.Builder()
val runtimeSettings = builder
.telemetryDelegate(GeckoGleanAdapter()) // Sets up the delegate!
.build()
// Create the Gecko runtime.
GeckoRuntime.create(context, runtimeSettings)
```
#### Adding new metrics
New Gecko metrics can be added as described [in the Firefox Telemetry docs](https://firefox-source-docs.mozilla.org/toolkit/components/telemetry/telemetry/start/adding-a-new-probe.html).
