+This article explains how to build the ONAP Policy Framework and get it running in Docker as a standalone system. 
+This article assumes that:
 
 * You are using a *\*nix* operating system such as linux or macOS.
 * You are using a directory called *git* off your home directory *(~/git)* for your git repositories
 * Your local maven repository is in the location *~/.m2/repository*
+* You have added settings to access the ONAP Nexus to your M2 configuration, see `Maven Settings Example <https://wiki.onap.org/display/DW/Setting+Up+Your+Development+Environment>`_ (bottom of the linked page)

+Cloning the ONAP repositories
+-----------------------------
+
+Run a script such as the script below to clone the required modules from the `ONAP git repository <https://gerrit.onap.org/r/#/admin/projects/?filter=policy>`_. This script clones the ONAP policy code and also clones some modules that ONAP Policy is dependent on.
+
+ONAP Policy requires all the *policy* modules from the ONAP repository. It also requires the ONAP Parent *oparent* module and the ONAP ECOMP SDK *ecompsdkos* module.

 Building the ONAP Policy Framework Docker Images

+------------------------------------------------
+The instructions here are based on the instructions in the file *~/git/onap/policy/docker/README.md*.
+
+
+**Step 1.** Build the policy engine docker image:
+
+		.. code-block:: bash 
+
+		    cd ~/git/onap/policy/engine/packages/docker/target
+		    docker build -t onap/policy-pe policy-pe
+
 
-**Step 1.** Prepare the Docker packages. This will pull the installation zip files needed for building the policy-pe and policy-drools Docker images into the target directory. It will not actually build the docker images; the additional steps below must be followed to actually build the Docker images.
+**Step 2.** Build the Drools PDP docker image:
 
-    * cd ~/git/onap/policy/docker
-    * mvn prepare-package
+		.. code-block:: bash 
 
-**Step 2**. Copy the files under *policy-pe* to *target/policy-pe*.

+		    docker build -t onap/policy-drools policy-drools
 
-    * cp policy-pe/* target/policy-pe
 
-**Step 3**. Copy the files under *policy-drools* to *target/policy-drools*.
+**Step 3.** Build the Policy Nexus docker image:
 
-    * cp policy-drools/* target/policy-drools
+		.. code-block:: bash 
 
-**Step 4**. Run the *docker build* command on the following directories in the order below. 
-Note that on some systems you may have to run the *docker* command as root or using *sudo*.
+		    cd ~/git/onap/policy/docker
+		    docker build -t onap/policy-nexus policy-nexus
 
-    * docker build -t onap/policy/policy-os     policy-os

 Starting the ONAP Policy Framework Docker Images
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+------------------------------------------------
+
 In order to run the containers, you can use *docker-compose*. This uses the *docker-compose.yml* yaml file to bring up the ONAP Policy Framework.
 
-**Step 1.** Make the file *config/drools/drools-tweaks.sh* executable

+**Step 1.** Make the file config/drools/drools-tweaks.sh executable.
+
+		.. code-block:: bash 
+
+		    chmod +x config/drools/drools-tweaks.sh
+
+
+**Step 2.** Set the IP address to use to be an IP address of a suitable interface on your machine. Save the IP address into the file *config/pe/ip_addr.txt*.
+
+
+**Step 3.** Set the environment variable *MTU* to be a suitable MTU size for the application.
+
+		.. code-block:: bash 
+
+		    export MTU=9126
+
+
+**Step 4.** Determine if you want policies pre-loaded or not. By default, all the configuration and operational policies will be pre-loaded by the docker compose script. If you do not wish for that to happen, then export this variable:
 
-    * chmod +x config/drools/drools-tweaks.sh
+		.. code-block:: bash 
 
-**Step 2**. Set the IP address to use to be an IP address of a suitable interface on your machine. Save the IP address into the file *config/pe/ip_addr.txt*.
+		    export PRELOAD_POLICIES=false
 
-**Step 3**. Set the environment variable *MTU* to be a suitable MTU size for the application.
 
-    * export MTU=9126
+**Step 5.** Run the system using *docker-compose*. Note that on some systems you may have to run the *docker-compose* command as root or using *sudo*. Note that this command takes a number of minutes to execute on a laptop or desktop computer.
