Create documentation walkthrough for constructing OSCAL Profiles

[david-waltermire]

User Story:

As a OSCAL content creator, I need to know how to 1) tailor an existing baseline or 2) create a new baseline representing a collection of selected controls. I need to have access to documentation that guides me step-by-step through these two use cases.

Goals:

• Documentation is provided that walks a content creator through tailoring an existing Profile, to include adding and removing controls, and customizing parameter labels and values.
• Documentation is provided that walks a content creator through creating a new Profile, to include selecting and customizing controls, detailing groupings of controls, and customizing parameter labels and values.
• Documentation provides links to Profile documentation on the data elements used in constructing a profile.

Dependencies:

• General Profile documentation explains the data elements used to construct an OSCAL Profile.

Acceptance Criteria

• A walk through is provided that illustrates tailoring of an existing profile using all available Profile features.
• A walk through is provided that illustrates creation of a new profile using all available Profile features.
