    cd flask-admin

2. Create and activate a virtual environment::

    virtualenv env
    source env/bin/activate

3. Install requirements::

    pip install -r 'examples/geo_alchemy/requirements.txt'

4. Setup the database::

    psql postgres

    CREATE DATABASE flask_admin_geo;
    CREATE ROLE flask_admin_geo LOGIN PASSWORD 'flask_admin_geo';
    GRANT ALL PRIVILEGES ON DATABASE flask_admin_geo TO flask_admin_geo;
    \q

    psql flask_admin_geo

    CREATE EXTENSION postgis;
    \q

5. Run the application::
