+Positioning
+===
+
+This plugin adds a positioning test tool in every course.
+Positioning tests should be used before and after any course. One initial test should be taken before anything else is used in the course, and a final test (usually a copy of the same test) should be used at the end. A radar-chart will show the differences between the initial test and the final test for each learner.
+
+For a test to be used as initial or final test, it has to match 3 criteria:
+ - use at least 3 question categories
+ - use the "radar" type result page
+ - have only one available attempt
