KM: DMS- how to get startet with the KM?

Hello,

I'm quite a newcomer in the area of SAP NetWeaver Portal. I want to use the KnowledgeManagement as a Document Management System where I can store documents and search for them with the help of TREX. Also the Collaboration-Part sounds very interesting to me.

Can anyone tell me how to get startet with KM? Are there any step-by-step tutorials? How to enter data into the system? I read something about taxonomie and indexing but I realy need help!

Thanks!

Sandy
