+There are 3 approaches to install ONAP:
+
+* Full ONAP installation using Heat template
+* Advanced installation to install individual components
+* Experimental installation using Kubernetes
+
+Full ONAP installation using Heat template
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+From a complete demo solution perspective. This installs the whole ONAP,
+refer to :ref:`Setting Up ONAP <demo-installing-running-onap>`.
+
+Advanced installation to install individual components
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+From a developer perspective, ONAP can be installed component per component.
+For details, refer to :ref:`the installation procedure available for each
+component<index-setting-individual-components>`.
+The advanced installation procedure is recommended only for experienced
+developers who desire to focus their attention on a few components and who have
+a deep understanding of dependencies between components.
+This type of installation is not recommended to fully install ONAP.
+
+* The list of ports used by default within ONAP is documented in
+ `ONAP Service List <https://wiki.onap.org/display/DW/ONAP+Services+List>`_.
+
+* The ONAP Source Code is available through Gerrit at https://gerrit.onap.org
+ or Git at https://git.onap.org/.
+
+* ONAP is packaged within Docker and can be dowloaded from Docker Hub at
+ https://hub.docker.com/r/onap.
