# Configuration Options
You can pass an options object when you call `ShareButton` on an element to make things a little more flexible.

Passing configuration options:

```js
config = {
    networks: {
        facebook: {
            app_id: '12345'
        }
    }
}

var share = new ShareButton('.share-button', config);
```

All options:

```js
config = {
  protocol:     // the protocol you'd prefer to use. [Default: your current protocol]
  url:          // the url you'd like to share. [Default: `window.location.href`]
