+Pitfalls
+--------
+
+If you get ``"failed to import extension evolve: No module named 'evolve'"``
+error, there are a couple of things to check:
+
+* make sure you gave pip the correct package name (it's hg-evolve),
+
+* make sure evolve is installed for the same version of Python that you use for
+  running Mercurial (``hg debuginstall | grep Python``).
