Since the FirstSpirit version 4.2 the API contains a lot of examples.
Each of these examples is shown with syntaxhighlighting and comes along with a large number of detailed comments, which explains the code of the example step by step.
The list of all available examples can be opened with the two API-links "All Examples" and "Examples" at the upper end of your display.
The only difference between both links is the short teasertext you get to each entry with the link "Examples".
link-target of "All Examples":
link-target of "Examples":
Furthermore it is possible to open an example with the link in the JavaDoc-comment of the class, which is explained by the example.
