Thanks for the message.
What exactly are you trying to do? Have you got ARK up and running and working with the single context system in there? If so you should be able to navigate around and enter data, etc. in there.
It is difficult to know exactly how you want to setup your database without having seen your paper records. How close are those records to the MoLAS Single Context recording system? If they are the same then you should be able to just enter the data straight into ARk without any special customisations.
However, if they are different or if you want to add new types of data (fields) or new modules/items, that is a bit of a different matter.
The ARK wiki has three different levels, User, Admin and Developer. I would suggest you want to check out the Administrator Section (http://ark.lparchaeology.com/wiki/index.php/Administrator_Manual
). In particular you will want to check out the settings file explanations (and also the in-line explanations in the settings files themselves - in the config/ directory).
Sorry to be so vague, but if you could let us know a bit more about exactly what you are trying to do then hopefully we'll be able to help a bit more!
