should we have wiki pages describing how gem works?

[iffyuva]

although code contains detailed description, should we have wiki pages?

points to consider:

• how different ledger items like invoices, credit-notes and payments work together
• how line items work, and how one can extend it.
• how taxing works, and how tax rates can be evolved.

we can write documentation and generate docs wiki can be be for edge-cases and specific details

the points you mentioned, sounds like good candidates for a wiki page
