Clone the repository:

$ https://github.com/<user_name>/ehealth_backend.git

Installing the Requirements::

$ cd ehealth_backend
$ source path/to/env/activate
$ python -m pip install -r requirements.txt

Setting up Postgres:

CREATE SUPERUSER:

    $ createuser --interactive <username>

CREATE USER:
    
    $ sudo -u postgres psql

    postgres=# CREATE USER <username> with PASSWORD '<password>';
    
        IF Output == CREATE ROLE, then exit from the postgres terminal by pressing "\q"

    postgres=# \q 

CREATE DB:

    default hostname: 127.0.0.1

postgresql://admin:admin@localhost:5432/eHealth
