Live Id. How Can I Intergrate? I need to use Live ID in my web application

I'm developing a web application and want to use Live ID (check out https://dev.onedrive.com/sdks.htm for more details).

Do you know any document so that I can get started. I check out the white page but it doesn't help. That's just a introduction. I need a how-to.

Well there may not be a how-to that teaches exactly what you need to know, but I found on that very same page this link:

https://dev.onedrive.com/sdks.htm

It seems to have some useful resources such as a forum, an SDK, and the "API Poster." But usually Microsoft is kind of stand-offish with their documentation, so unless you can find a third party one out there somewhere, the forum would probably be the best resource.

Hope this helps,
Jared
