 Copy the config.sample.json file and rename to config.json. Be sure to update the fields as you see appropriate. You have the option to use the Unsplash API to fetch background images, or use a custom URL and JSON selector. If you choose to use Unsplash, will need to create a developer profile at [Unsplash](https://unsplash.com/) to use the background image functionality properly.

 ### Custom Background Images
-- 'custom_url' => Input a custom URL that will return proper JSON
-- 'custom_url_headers' => Add any headers that may be needed to complete a cURL request to the aforementioned URL properly
-- 'custom_url_selector' => Input a proper PHP array selector to be used on the JSON received above. For example, if I were to fetch from Github's user API with a 'custom_url' of 'https://api.github.com/users/octocat', the 'custom_url_selector' would simply be "['avatar_url']". [{random}] can be replaced for a random index in an array.
