+Using the provisioning scripts
+==============================
+
+Vagrant is a platform that uses prebaked images called
+*vagrant boxes* to guarranty that running multiple times a
+provisioning script will result in an expected output. This
+mechanism is crucial for reducing the number of external factors
+during the creation, development and testing of provisioning scripts. 
+However, it's possible to provide an ONAP development enviroment
+without having to install Vagrant tool. This document explains how to
+consume the provisioning scripts localed in **./lib** folder to
+provision a development environment and the environment variables
+that modifies their behavior.
+
+This project was built on an Ubuntu 14.04 ("Trusty") Operating System,
+therefore it's necessary to have an user who has *sudo* permissions to
+access to a Bare Metal or Virtual Machine.
+
+The following instructions retrieve the provisioning scripts and place
+them into the */var/onap/* folder.
+
+.. code-block:: console
+
+    $ sudo apt-get install git -y
+    $ git clone https://git.onap.org/integration/devtool
+    $ cd /var/
+    $ ln -s ~/devtool/lib/ ./onap
+
+.. end
+
+Loading a provisioning script will be based on the desired ONAP
+service, for example to setup the development environment for Active
+and Available Inventory (AAI) service will be required to load the
+*/var/onap/aai* script.
+
+.. note::
+
+    The **git_src_folder** environment variable specifies the
+    source code destination folder, it's default value is */opt/onap/*
+    but it can be changed only after is loaded the provisioning
+    scripts.
+
+.. end
+
+.. code-block:: console
+
+    # source /var/onap/aai
+
+.. end
+
+Lastly, every script has defined a initialization function with
+*init_* as prefix. This function is the starting point to provision
+the chosen ONAP service. This example uses the *init_aai* function
+to provision a AAI Developement environment.
+
+.. note::
+
+    The **compile_repo** environment variable defines whether or not
+    the source code located on the repositories of the service.
+    Enabling this value can impact the provisioning time of the
+    service.
+
+.. end
+.. note::
+
+    **nexus_docker_repo**, **nexus_username** and **nexus_password**
+    environment variables specify the connectivity to a private Docker
+    Hub.
+
+.. end
+.. note::
+
+    **build_image** environment variable allows the Docker images
+    from source code.  Enabling this value can impact the
+    provisioning time of the service.
+
+.. end
+
+.. code-block:: console
+
+    # init_aai
+
+.. end
+
+As result, the source code is pulled into */opt/onap/aai/* folder and the
+AAI services are up and running with the proper connection to the
+Titan Distributed Graph Database.
