+Pod Description File
+********************
+
+The PDF(Pod Descrition File) provides template for POD's hardware information for all the
+installers in yaml. The target is to use the same PDF file to deploy a POD by any installer with
+any scenario it supports. It is the base of the dynamic CI , LaaS(Lab as a Service) and
+SDF(Scenario Description File).
+
+Currently Jinja template is used to transfer the PDF to the specific installer's
+template. PDF, Jinja template and the transfering tools are all stored in :ref:`securedlab`.
+You can find the latest PDF template in
+https://gerrit.opnfv.org/gerrit/#/c/38283/8/labs/lf/pod4.yaml.
