{{Hint|Unless the activity is of type ''FlowChart'' or ''Sequence'', you will not be able to add more than one Activity to the canvas}}
Typically you we want to start with a Sequence or a Flowchart, which are both able to host child (nested) Activities
* The Sequence executes its nested Activities sequentially, one after the other
* The FlowChart executes its nested Activities in the order you link them with connecting lines
