New user here, which version should I download?

I am a brand new user and I am wondering which version to download ?
I would like a version that “matches” the available documentation and examples.
Should I DL jMonkeyEngine 3.1 alpha 4 or is it better to go with jMonkeyEngine 3 SDK from the downloads section ? (
I use NetBeans btw.

Thanks for any input on this!

Use 3.0, 3.1 is in alpha and may cause unexpected behavior, its intended for people who know the engine and can give feedback on issues in the alpha.

Thank you normen !!
