 Before we move on to the section of building a new model, let's take a look at
 the development workflow of Cornac.
 
-The main workflow of developing a new model will be to:
-
-``Create an example, Create model files --> Build --> Run Example``
+First time setup
+^^^^^^^^^^^^^^^^
 
-Whenever a new change is done to your model files, you are required to rebuild
-Cornac using the ``setup.py`` script. This will ensure that the changes you have
-made to your model files are reflected in the Cornac package.
+As Cornac contains models which uses Cython, compilation is required before
+testing could be done. In order to do so, you need to run the following command:
 
+.. code-block:: bash
 
-Rebuilding Cornac
-^^^^^^^^^^^^^^^^^
+    python setup.py build_ext —inplace
 
-1. To build Cornac on your environment:
+This will compile the Cython files and place the compiled files in the
+``cornac/models`` folder.
 
-.. code-block:: bash
 
-    python3 setup.py install
+The main workflow of developing a new model will be to:
 
+1. Code model files
+2. Code example
+3. Run Example
 
-.. note::
+Folder structure for testing
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-    The following packages are required for building Cornac on your environment: ``Cython``, ``numpy``, ``scipy``.
+.. code-block:: bash
     
-    If you do not have them, install by using the following commands:
+    cornac
+    |-- cornac
+    |   |-- models
+    |       |-- mymodel
+    |       |   |-- __init__.py
+    |       |   |-- recom_mymodel.py
+    |       |-- requirements.txt
+    |-- mymodel_example.py <-- not in the examples folder
 
-    .. code-block:: bash
+To run the example, ensure that your current working directory is in the top
+``cornac`` folder. Then, run the following command:
+
+.. code-block:: bash
 
-        pip3 install Cython numpy scipy
+    python mymodel_example.py
 
-2. Run an example utilising your new model.
+Whenever a new change is done to your model files, just run the example for
+testing and debugging.
