experiences with YAML and where to place?

Are you using YAML, the css-framework?
What are your experiences?
Where do you place it on your server?

[Till now I did not use a framework and I'm not involved in all css-tricks. So I think it might be useful to me starting with a css framework. Developed by a community it should always be state of the art..]
