 == defer ==
 
-`defer`
+`defer` adds the function call after the keyword to a stack. All of the calls
+on that stack are called when the function in which they were added returns.
+This means that they are called in filo order.
+
+This is useful because we can add the code to cleanup a resource to this
+`defer` stack when its initilized, and then we do not have to remember to clean
+it up later.
+
+== flag ==
+
+`flag` is a package for parsing cli flags. This supports
+
+{{{
+-flag=x
+-flag x
+--flag=x
+--flag x
+
+-boolflag
+--boolflag
+-boolflag=value
+--boolflag=value
+  }}}
