+An ''Activity'' is an action that is performed during your process. In Galaxia activities are mapped to PHP scripts so an activity can do anything that can be done from a PHP script. A process can consist of many activities. By default, a ''start'' and ''end'' activity are created for you, but these can be renamed or deleted at a later stage. I'll define two other terms so you can understand their context later.
 
 An ''instance'' is a particular process currently being executed. An activity can have many instances associated with it at any time. An instance is created when a process is initiated by a user and the instance will pass through the process activities until the process is terminated or completed.
 
 A ''transition'' is the path between two or more activities. A transition defines what has to be done after each activity is completed.
+
+A ''workitem'' is added to the instance when an activity is completed. Workitems thus represent completed activities.
 
 Activities are broken up into different types. Here are two types listed below:

 Let me explain these lines.
-The first line ''$smarty->assign('display_text', 'Hello world!');'' is used to assign text to a ''variable'' which is used in __template__. Here we are assigning the variable ''display_text'' with the words '''Hello world!'''. You will see this used when we edit the template section.
