# Using Leaf

This section outlines how to import the Leaf package both with or without a Vapor project.

## With Vapor

The easiest way to use Leaf with Vapor is to include the Leaf provider. 

```swift
import PackageDescription

let package = Package(
    name: "Project",
    dependencies: [
        .Package(url: "https://github.com/vapor/vapor.git", majorVersion: 2),
        .Package(url: "https://github.com/vapor/leaf-provider.git", majorVersion: 1)
    ],
    exclude: [ ... ]
)
```

The Leaf provider package adds Leaf to your project and adds some additional, Vapor-specific conveniences like `drop.stem()`. 

Use `import LeafProvider`.

## Just Leaf

At the core of the Leaf provider is a fast, pure Swift templating engine. You can use it with any of your Swift packages or server-side Swift applications.

```swift
import PackageDescription

let package = Package(
    name: "Project",
    dependencies: [
        ...
        .Package(url: "https://github.com/vapor/leaf.git", majorVersion: 2)
    ],
    exclude: [ ... ]
)
```

Use `import Leaf` to access the `Leaf.Stem` class.
