From your home directory:
$ git clone https://github.com/tboggs/emacs-config.git .emacs.d
$ ln -s .emacs.d/.emacs
Note that this will clobber your existing emacs configuration.
If they're not already installed in your virtualenv
pip install epc jedi
After starting emacs, switch to the virtualenv and install the jedi server:
M-x venv-workon RET <virtualenv name>
M-x jedi:install-server
You may need to restart and possibly install the server again. If packages get installed under ~/.emacs.d/.python-environments, then you will most likely need to delete that directory and try again.
