 not need to declare account types, as they will be detected
 automatically using the following rules:
 
-| If name matches this [regular expression]: | account type is:
-|----------------------------------------------|-----------------
-| `^assets?(:|$)`                              | `Asset`
-| `^(debts?|liabilit(y|ies))(:|$)`             | `Liability`
-| `^equity(:|$)`                               | `Equity`
-| `^(income|revenue)s?(:|$)`                   | `Revenue`
-| `^expenses?(:|$)`                            | `Expense`

-| If account type is `Asset` and name does not contain this regular expression: | account type is:

 Even so, explicit declarations may be a good idea, for clarity and
 predictability.
