+
+To install a complete development environment for InvenTree, follow the steps presented below.
+
+A makefile in the root directory provides shortcuts for the installation process, and can also be very useful during development.
+
+Installation
+------------
+
+All packages required to develop and test InvenTree can be installed via pip package manager. Package requirements can be found in ``requirements.txt``.
+
+To setup the InvenTree environment, run the command
+
+``make install``
+
+which performs the following actions:
+
+* Installs all required Python packages using pip package manager
+* Generates a SECREY_KEY file required for the django authentication framework
+
+Superuser Account
+-----------------
+
+Run ``make supeuser`` to create a superuser account, required for initial system login.
+
+Run Development Server
+----------------------
+
+Run ``python InvenTree/manage.py runserver`` to launch a development server. This will launch the InvenTree web interface at ``127.0.0.1:8000``. For other options refer to the `django docs <https://docs.djangoproject.com/en/2.2/ref/django-admin/>`_.
+
+Database Migrations
+-------------------
+
+Whenever a change is made to the underlying database schema, database migrations must be performed. Call ``make migrate`` to run any outstanding database migrations.
+
+Development and Testing
+-----------------------
+
+Other shorthand functions are provided for the development and testing process:
+
+* ``make test`` - Run all unit tests
+* ``make coverage`` - Run all unit tests and generate code coverage report
+* ``make style`` - Check Python codebase against PEP coding standards (using Flake)
+* ``make documentation`` - Generate this documentation
