============
How it works
============

If you want to create and deploy an app on deepchain hub, you could use the command provided in the deepchain-apps package. 
Below are the main commands that should be used in a terminal:

Basic cli
---------

After installing deepchain-apps package, you will be able to use the CLI directly inside the terminal.

1. Put your personal access token (PAT) to deploy the application on `deepchain.bio <https://deepchain.bio/>`_

.. code-block:: bash

    deepchain login

2. Create an application based on an empty template.

.. code-block:: bash

    deepchain create myapplication

This command will download the template hosting on github in the folder **myapplication**

3. Or download a pre-existing app. First list available apps.

.. code-block:: bash

    >> deepchain apps --public

    ----------------------------------------------
    APP                                 USERNAME             
    ----------------------------------------------
    FullInfluenzaBinding                 k.eloff     
    OntologyPredict                    stj.grimbly    
    DiseaseRiskApp                     jb.sevestre  
  


    Download app command  :  deepchain download username/app app

    Apps description at : https://app.deepchain.bio/hub/apps

Then download and modifies it.

.. code-block:: bash

    deepchain download user.name/appname myapplication


After creating or downloading an app, you can build your own scorer function as explained `here <https://deepchain-apps.readthedocs.io/en/latest/tutorial/apps_building.html>`_.

This `section <https://deepchain-apps.readthedocs.io/en/latest/documentation/deepchain.html>`_ provide you some insights on how to use your app in DeepChain™.

4. Finally, you can deploy your application on deepchain. After validation, it will be available on the deepchain public `hub <https://app.deepchain.bio/hub/apps>`_

.. code-block:: bash

    deepchain deploy myapplication
