 ## INTERACTIVE ELEMENTS *interactive*
 
 As visible in this very document, vim-tutor-mode includes some interactive
-elements, to provide feedback to the user about his progress. These elements
-all have the syntax
-
-    \---> TEXT {CLAUSE}

-where \---> must start at the beginning of the line. If TEXT satisfies CLAUSE,
-a ✓ sign will appear to the left. A ✗ sign is displayed otherwise. The CLAUSE

+elements to provide feedback to the user about his progress. If the text in
+these elements satisfies some set condition, a ✓ sign will appear in the gutter
+to the left. Otherwise, a ✗ sign is displayed.
 
 ### expect *expect*
 
-The basic clause is "expect", which is satisfied if TEXT is the same as the
-content of the clause. For example
+"expect" lines check that the contents of the line are identical to some preset text
+(like in the exercises above).
 
-    \---> TEXT {expect:TEXT}
+These elements are specified in separate JSON files like this
 
-is satisfied, but

+	"2": "This is how this line should look.",
+	"3": -1
+    }
+}
+~~~
 
-    \---> OTHER TEXT {expect:TEXT}
+These files contain an "expect" dictionary, for which the keys are line numbers and 
+the values are the expected text. A value of -1 means that the condition for the line
+will always be satisfied, no matter what (this is useful for letting the user play a bit).

-If the content of a expect clause is ANYTHING, no checks will be performed. This is
