BeginHere is a web application, and the structure follows
that of a Django project.

2.3 Installation

Step 1. Clone the repository
    git clone https://github.com/tonnpa/begin-here.git
    cd begin-here

Step 2. Set up virtual environment with required packages
    From here onwards, we assume the current
    working directory is ~/begin-here
    - Activate the virtual environment
    virtualenv venv
    - Install required packages
    pip install -r requirements.txt

Step 3. Set up the database
    - Create the database tables
    python manage.py migrate

Step 4. Populate the database
    - Download the snapshot of our database containing
    the model instances with cleaned and aggregated
    attributes from:
    https://app.box.com/s/x6b75wp0hns3djr1ocxphjed15hhjh7y
    - Place the snapshot.json into the folder 
        ~/begin-here/foodmap/fixtures
    - Load the data
    python manage.py loaddata snapshot

Following these steps, the web server could be started with
    python manage.py runserver
And the user should be able to access the homepage at the
assigned port.
