First you need python 3 then:
Go to wall/backend directory and
$ pip install -r requirements.txt
$ python manage.py runserver
and go to http://127.0.0.1:8000/ it should be enough.
One thing:
- the welcome email will be printed on the console (using
django.core.mail.backends.console.EmailBackend) since I didn't set a SMTP server.
If you'd like to run the frontend's development version go to wall/frontend directory and
$ npm install
$ webpack-dev-server
and you're good to go.
