[opencms-dev] Content Definitions Help

[Kevin Durley]

Help!

I am having a problem understanding Content Definitions.

I understand the principal and I think it is what I need but ... how do 
I create/define them?

I don't know where to start!

Do I really have to manually create tables in the MySQL database?

How does the 'user interface' (where the user enters the actual data) 
get created?

I have imported a module (another thing I'm confused about) that I 
downloaded relating to Content Definitions and I can see that is 
contains loads of files but I have no idea how they relate or how and 
why they are in this particular structure.

Basically I'm lost and would be very grateful if somebody could PLEASE 
show me (in basic terms) how to create a Content Definition.

Many thanks in advance ;-)
