Hi @shannonAB,

Thanks for the PR!
Having gone through your code and having tested it, here are my review comments:

1. Your SERVER_URL is not using https. It's a strict requirement that Prebid.js v3.0.0 onwards all adapters use a secure endpoint.

2. The examples given in your markdown file is not accurate. Again, with Prebid.js v3.0.0 onwards, the property sizes in adUnit object is no longer supported. Instead, you should use the mediaTypes property. For example, in case of a banner ad, you should use,

mediaTypes: {
  banner: {
    sizes: [[728, 90]]
  }
}

Details about the Prebid.js v3.0.0 release.

3. Am getting a 404 BAD REQUEST on sending a request to your endpoint. I tested with the hello world page

I've attached a screenshot for your reference.

@shannonAB,

Thanks for making the changes. I was expecting one more thing in your md file, since you support native and video formats as well, can you provide some examples of those. It'll be easier for us to test that way.

LGTM!
