Attendee registration form

Hi,
I can’t seem to find this information clearly explained anywhere…
If I use the free version of the plugin, can I set a simple registration form for the events? (like collecting name and contact information)
I have found some discussion stating that you can with some predefined fields, but cannot find any option after installing.
I do not even see any mention in the description of the pro version, which seems to add payment features for the events, but no words about introducing a free registration are spent.

Could you please help to understand how to accomplish it?
I simply need to be able to put a registration form in the details of events, so that visitors can leave their data to be registered.

If this is already documented, and I just could not see it, please point me to the right article.

Thanks a lot!
