+### I want to serve card images, audio stream etc. over HTTP not HTTPS
+
+In some special cases, you may be allowed to serve content over HTTP instead of HTTPS. To allow this within Ralyxa, you need to set the `require_secure_urls` configuration option to false.
+
+> **NOTE:** In order to use HTTP sources, you must be given special approval directly from Amazon. If you use HTTP sources without getting advanced approval, your skill will not work correctly.
+
+```ruby
+Ralyxa.configure do |config|
+  config.require_secure_urls = false

 ## Testing
 Part of Amazon's requirements for Alexa skills is that they have to ensure requests are sent from Amazon. This is done in a number of ways documented [here](https://developer.amazon.com/docs/custom-skills/host-a-custom-skill-as-a-web-service.html). This verification is built into Ralyxa and can cause issues when testing your skills with stubbed data.
 
 ### Disabling verification
