Access PDM application or PDM capabilities pages

As an internal user, I need to access the following pages to navigate the PDM application or PDM capabilities built within Concourse:
- A landing/home page
- A page that provides background on PDM
- A page that provides a visual overview of the methodology that users can drill down on to access the content

Reason: It will be helpful to the (new) user to understand the general background of PDM
