+First, copy `pythonkc_site/.env.example` to `pythonkc_site/.env` and add
+your own [meetup api key][] and a unique [django secret key][] (`.env` will
+be ignored by git)

+Then you have to install some vagrant plugins and build your vagrant box:

 ```
 vagrant plugin install vagrant-hostmanager

+Now go to `http://192.168.100.101:8000` in your browser. You can edit the files
+on your local machine and the server should reload automatically.

+For now, this is a Python 2 project. If you want to start using Python 3
+and help us fix our problems, set Ansible's `python_version` variable to 3
+and it will build the virtualenv using Python 3:

+ansible-playbook vagrant.yml -e python_version=3
