 - (4) and (5) [Optional] To style a node, the method `nodeStyle` is used. It accepts a lambda function, in which the style of every node can be customized by calling methods on the given `Style` object, e.g. setting the name (5) or background color (6). The default name is to use the class name along with the hashcode of the object (`node == null ? "null" : node.getClass().getSimpleName() + "@" + Integer.toHexString(node.hashCode())`).
 - (6) [Optional] To style a relation, the method `relationStyle` is used. It is used similar to `nodeStyle`, but is called with source and target node of a relation (containment and non-containment). Note, that (a) the default label can be retrieved with `style.getLabel()`, (b) `target` can be `null` for lists, (c) secondary connections from a list node to the target nodes use the style of the relation and use their index as label.
 - (7) [Optional] There are a few ways to style the output in general through [SkinParam](https://plantuml.com/de/skinparam). Not all of those parameters are supported; see `SkinParamBooleanSetting` and `SkinParamStringSetting`.
-- (8), (9) and (10) To create an output image, use `dumpAsPng` for PNG (`dumpAsSVG` for SVG). Those methods do not return the builder object, as they produce an output. They potentially throw two kinds of exception: `IOException` (when the file could not be written) and `TransformationException` (when the AST could not be processed). As shown here, the builder object must be stored in a variable to create multiple outputs. Alternatively to a file, the result can be written to a given `OutputStream` (10).

 To summarise the required steps: Specify the AST to read in, configure the output, and write ("dump") the output.
