+## Check list
+
+- [ ] I read \"Avoid standard Emacs traps\" section in
+  https://github.com/tkf/emacs-ipython-notebook/blob/master/CONTRIBUTING.md
+- [ ] I checked that IPython works with the browser interface.
+- [ ] I checked that the problem was not due to badly compiled
+  files.  Removing `*.elc` files from source directory of EIN and
+  its dependencies did not solve the problem.
+- [ ] I checked that the libraries are loaded from intended place.
+  (You can check the location in the \"System info\" section below)
