+A few more things
+
+@content
+* ++If the `hyperref` package is used before `cleveref`, cross-references appear as **clickable links** in the PDF document.

+* ++On the second page of the document, insert a paragraph about the LaTeX weekend with `\cref` **references** to some of the sections you’ve been working on. You might have to assign labels first.
+* ++Wrap a `figure` environment around the **listings from task 9** (section 2.4).
+* ++Add a **label** and **caption** to each of them.
