# Using Validation

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

## With Vapor

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

    import PackageDescription

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

The Validation provider package adds Validation to your project and adds some additional, vapor-specific conveniences like validation middleware.

Using `import ValidationProvider` will import the Validation middleware and the Validation module.

## Just Validation

At the core of the Validation provider is a Validation module.

    import PackageDescription

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

Use `import Validation` to access the core validation class.
