+#### PYTHON 3 MIGRATION
+
+We are migrating to Python 3!  Also, yikes!
+
+Currently building on `Python 3.6.4` and `Pelican 4.0.1`.
+
+This is on branch `migrate/py3`.
+It's easiest to use a virtual environment to work in this, so once you've sorted out Python 3.6.4 being 
installed, you can run:
+
+```
+python3 -m venv py3-venv
+```
+
+This will make the virtual environment folder at `py3-venv`, which is already in `.gitignore`.
+
+To activate, as usual, `source py3-venv/bin/activate`.
+To de-activate, `deactivate`.
+

 ###  Pelican configuration files (pelicanconf.*)
 The main settings file to build the site is pelicanconf.*.
