# [Android Components](../../../README.md) > Concept > Base

A component for basic interfaces needed by multiple components and that do not warrant a standalone component.

## Usage

Usually this component is not used by apps directly. Instead it will be referenced by other components as a transitive dependency.

### 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:concept-base:{latest-version}"
```
