+
+Version 2.2.0 of this extension brought support for the flowchart useMaxWidth configuration parameter. It prevents
+the respective chart from being resized to fit the size of the screen.
+
+It is passed to the parser function like shown:
+```
+{{#mermaid:graph LR;
+ ...
+ |
+ config.flowchart.useMaxWidth = false
+}}
+```
+Note that is is also possible to further adapt the graph using CSS, e.g. to add a scrollbar:
+
+```
+.ext-mermaid > div {
+	overflow: scroll;
+}
+```
+
 Further [examples][examplesmw] have been created on wiki.
