+As a teacher, first create an account from the upper-left "login" menu.
+Then create a course using the appropriate button in the middle of the screen.
+Finally, create some exams ("new assessment" button). The syntax for a series of questions is described by the following example:
+
+ > Global (HTML) introduction [optional]
+
+ Question 1 text or introduction (optional if there are subquestions)
+
+ Text for question 1.1 (index detected from indentation)
+ * Answer to 1.1
+
+ Question 1.2 (a text is optional since there are subquestions)
+
+ Question 1.2.1 text (mandatory); e.g. quiz-like:
+ + choice 1
+ - choice 2
+ - choice 3
+
+ Question 1.2.2 text (mandatory); e.g. open question:
+ * answer to 1.2.2 (can be on several lines)
+
+ Question 2 text ...
+ * An answer to question 2
+ ...
+
+All question texts (and open answers) can be on several lines.
+HTML markup (slightly limited) can be used, as well as [MathJax](https://www.mathjax.org/) with $ and $$ delimiters,
+and syntax highlighting using [prism](http://prismjs.com/): `<code class="language-xyz">` for language code `xyz`.
+The syntax for parameterized exercises (not working yet) is still undecided.
+
+Use the "exam" mode if browsing the web is allowed, and "watch" mode otherwise to monitor
+students actions like losing focus or resizing window.
+Finally the "secure" mode forbids all attempts to do anything else than focusing on the exam,
+but can be "a bit too much"; keep in mind next section if using it.
+All these modes restrict the access to a classroom. To open a series of question to the world,
+the "open" mode is for you.
