+# Course materials
+
+We can reuse many slides from last year, see the contents of this repository.
+
+We will provide the course materials and program via GitLab. So this GitLab
+project will be the course homepage.
+
+The old course homepage can still be found here, but will be deleted before the
+course starts: https://humgenprojects.lumc.nl/trac/humgenprojects/wiki/gitcourse
