Hi Paul,
Our documentation lives on docs.tryton.org. The account documentation lives under the Modules -> Financial Accounting -> Accounting section. This should give you an introduction to all the accounting concepts.
Tryton is designed to have a default value for most of the settings, so you only require configuration if you need to change default values. Once you activate a module that needs some special configuration a wizard will be automatically opened asking you to fill the details. For example, it is required to create a company and to create a account chart if you use the accounting module.
We know that our documentation needs to be improved and any help on this will be very welcome. Here are some topics that talk about it:
- Proposal to improve the documentation structure
- End User Documentation
- Documentation on the proper place
Indeed we are also valorating the possiblity of apling to google summer of docs.
Feel free to use our forum or IRC channels to ask your doubts. We will try to answer them as soon as possible.
