@clouden90 Rather than just referring to sections in the User's Guide, I think it is best to provide a direct link to section 5.2 and 2.5. I'm also concerned about the details of section 5.2 (Running the SRW App's Grid Configuration section) and 2.5 (There is no section 2.5 in the user's guide, Chapter 2 only goes to 2.2 Quick Start Guide's Building and Running the UFS SRW Application). Are you sure that these are the sections that you want to point to here?

Now that the Components.rst section has been updated to note that the sections are in the CCPP-SCM User's Guide, rather than the SRW App's User Guide, I will go ahead and approve these changes.

This is an emergency PR to add the CCPP-SCM documentation into the Components.rst file. This is required for an EPIC deliverable, so it is imperative that this gets reviewed as soon as possible so that it can get merged. Thank you very much!

Thanks for the review, @chan-hoo! I will now move forward with merging this work.
