## Usage

1. Generate your reCAPTCHA keys on http://www.google.com/recaptcha/intro/index.html

2. Include the artifact in your POM:

	```xml

	

		com.anton-johansson

		vaadin-recaptcha

		2.0.0

	

	```

3. Include the reCAPTCHA JavaScript in your UI:

	```java

	@JavaScript("https://www.google.com/recaptcha/api.js")

	public class CustomUI extends UI

	{

	    ...

	}

	```

    

4. Add the ```Recaptcha```-component to your UI:

	```java

	String siteKey = "...";

	String secretKey = "...";

	Recaptcha captcha = new Recaptcha(siteKey, secretKey);

	layout.addComponent(captcha);

	```

    

5. Optionally set extra properties on your component:

	```java

	captcha.setType(RecaptchaType.AUDIO);

	captcha.setTheme(RecaptchaTheme.DARK);

	captcha.setSize(RecaptchaSize.COMPACT);

	```

    

6. Validate the user input:

	```java

	if (!captcha.isVerified())

	{

	    ...

	}

    ```
