1. A concise explanation of the problem you're experiencing.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you're using, your operating system and browser.

Hi there,

I’m a little confused what you are asking, can you be more specific?

Cesium Documentation is online here.

That documentation is included in the Build/Documentation with Cesium downloads.
