+Production Deployment
+=====================
+
+This README provides documentation to help deploy Yaksh in a production
+environment. If you wish to take Yaksh on a trial run, here is a
+[Quickstart Guide]
+(https://github.com/FOSSEE/online\_test/blob/master/README.md)
+
+Pre-Requisite
+^^^^^^^^^^^^^
+
+1. Ensure `pip <https://pip.pypa.io/en/latest/installing.html>`__ is
+   installed
+2. Install dependencies using pip install -r requirements.txt
+3. Install MySql Server
+4. Install Python MySql support
+5. Install Apache Server for deployment
+
+Configure MySql server
+^^^^^^^^^^^^^^^^^^^^^^
+
+1. Create a database named ``yaksh`` by following the steps below
+
+   ::
+
+       $> mysql -u root -p    
+       $> mysql> create database yaksh
+
+2. Add a user named ``yaksh_user`` and give access to it on the database
+   ``yaksh`` by following the steps below
+
+   ::
+
+      mysql> grant usage on yaksh to yaksh_user@localhost identified
+      by 'mysecretpassword';
+
+      mysql> grant all privileges on yaksh to yaksh_user@localhost;
+
+3. Add ``DATABASE_PASSWORD = 'mysecretpassword'`` and
+   ``DATABASE_USER = 'yaksh_user'`` to online\_test/settings.py
+
+To deploy this app follow the steps below:
+
+1.  Clone this repository and cd to the cloned repo. 
+
+   ::
+
+       $ git clone https://github.com/FOSSEE/online\_test.git
+
+2.  Run:
+
+   ::
+
+       python manage.py makemigrations yaksh
+
+       python manage.py migrate yaksh 
+
+4.  First run the python server provided. This ensures that the code is
+    executed in a safe environment. Do this like so:
+
+    ::
+
+        $ sudo python yaksh/code_server.py
+
+    Put this in the background once it has started since this will not
+    return back the prompt. It is important that the server be running
+    *before* students start attempting the exam. Using sudo is necessary
+    since the server is run as the user "nobody". This runs on the ports
+    configured in the settings.py file in the variable "SERVER\_PORTS".
+    The "SERVER\_TIMEOUT" also can be changed there. This is the maximum
+    time allowed to execute the submitted code. Note that this will
+    likely spawn multiple processes as "nobody" depending on the number
+    of server ports specified.
+
+5.  The ``wsgi.py`` script should make it easy to deploy this using
+    mod\_wsgi. You will need to add a line of the form:
+
+    ::
+
+        WSGIScriptAlias / "/online_test/wsgi.py"
+
+    to your apache.conf. For more details see the Django docs here:
+
+    https://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/
+
+6.  Go to http://desired\_host\_or\_ip:desired\_port/admin
+
+7.  Login with your credentials and look at the questions and modify if
+    needed. Create a new Quiz, set the date and duration or
+    activate/deactivate the quiz.
+
+8.  Now ask users to login at:
+
+    ::
+
+        http://host:port/exam
+
+    And you should be all set.
+
+9.  Note that the directory "output" will contain directories, one for
+    each user. Users can potentially write output into these that can be
+    used for checking later.
+
+10. As Moderator user you can visit http://host/exam/monitor to view
+    results and user data interactively. You could also "grade" the
+    papers manually if needed.
+
+11. You may dump the results and user data using the results2csv and
+    dump\_user\_data commands.
+
+12. The file docs/sample\_questions.py is a template that you can use
+    for your own questions.
+
+13. Sometimes you might be in the situation where you are not hosted as
+    "host.org/exam/" but as "host.org/foo/exam/" for whatever reason. In
+    this case edit "settings.py" and set the "URL\_ROOT" to the root you
+    have to serve at. In the above example for "host.org/foo/exam" set
+    URL\_ROOT='/foo'.
+
+Installation & Usage
+^^^^^^^^^^^^^^^^^^^^
+
+To install this app follow the steps below:
+
+1. Clone this repository and cd to the cloned repo.
+   ``$ git clone  https://github.com/FOSSEE/online_test.git``
+
+2. Run:
+
+   ::
+
+       $ python manage.py makemigrations yaksh
+
+       $ python manage.py migrate yaksh
+
+3. Run the python server provided. This ensures that the code is
+   executed in a safe environment. Do this like so:
+
+   ::
+
+       $ sudo python -m yaksh.code_server # For Python 2.x
+
+
+       $ sudo python3 -m yaksh.code_server # For Python 3.x
+
+   Put this in the background once it has started since this will not
+   return back the prompt. It is important that the server be running
+   *before* students start attempting the exam. Using sudo is necessary
+   since the server is run as the user "nobody". This runs the number
+   ports configured in the settings.py file in the variable
+   "N\_CODE\_SERVERS". The "SERVER\_TIMEOUT" also can be changed there.
+   This is the maximum time allowed to execute the submitted code. Note
+   that this will likely spawn multiple processes as "nobody" depending
+   on the number of server ports specified.
+
+   You can also use a Dockerized code server (see below)
+
+4. Now, Run:
+
+   ::
+
+          python manage.py runserver <desired_ip>:<desired_port>
+
+5. Create a Superuser/Administrator:
+
+   ::
+
+       python manage.py createsuperuser
+
+6. Go to http://desired\_host\_or\_ip:desired\_port/exam
+
+   And you should be all set.
+
+7. Note that the directory "output" will contain directories, one for
+   each user. Users can potentially write output into these that can be
+   used for checking later.
+
+8. As admin user you can visit http://desired\_host\_or\_ip/exam/monitor to view results
+   and user data interactively. You could also "grade" the papers
+   manually if needed.
+
+Using Dockerized Code Server
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+1. Install
+   `Docker <https://docs.docker.com/engine/installation/>`__
+
+2. Go to the directory where the project is located cd
+   /path/to/online\_test
+
+3. Create a docker image. This may take a few minutes docker build -t
+   yaksh\_code\_server ./docker/Dockerfile\_codeserver
+
+4. Check if the image has been created using the output of, docker
+   images
+
+5. Run the invoke script using the command ``invoke start`` The command
+   will create and run a new docker container (that is running the
+   code\_server.py within it), it will also bind the ports of the host
+   with those of the container
+
+Deploying Multiple Dockers
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+1. Install
+   `Docker <https://docs.docker.com/engine/installation/>`__
+
+2. Go to the directory where the project is located at:
+   
+   ::
+
+       cd /path/to/online_test
+
+3. Build the docker images
+
+   ::
+
+       invoke build
+
+4. Run the containers and scripts necessary to deploy the web
+   application
+
+   ::
+
+       invoke deploy
+
+5. Use ``invoke deploy --fixtures`` to load the fixtures
+
+6. Create the superuser and moderator group
+   ::
+
+       invoke createsuperuser
+
+7. Stop the containers
+
+   ::
+
+       invoke halt
+
+8. Remove the containers
+
+   ::
+
+       invoke clean
+
+
+Additional commands available
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We provide several convenient commands for you to use:
+
+-  load\_exam : load questions and a quiz from a python file. See
+   docs/sample\_questions.py
+
+-  load\_questions\_xml : load questions from XML file, see
+   docs/sample\_questions.xml use of this is deprecated in favor of
+   load\_exam.
+
+-  results2csv : Dump the quiz results into a CSV file for further
+   processing.
+
+-  dump\_user\_data : Dump out relevalt user data for either all users
+   or specified users.
+
+For more information on these do this:
+
+::
+
+        $ python manage.py help [command]
+
+where [command] is one of the above.
