Importing Management Packs from the Catalog, and downloading the MP guide.
When importing a Management Pack directly from the Management Pack Catalog to OpsMgr 2007 R2 you don’t get the chance to read the MP documentation. Becouse you do the download and import of the MP at the same time.
Most of the Management Packs got pre-install instructions in the documentation that you want to read.
So, to be able to download the documentation:
In the Select Management Packs from Catalog, search for the MP that you are about to import.
Mark the product and klick to Properties on the right.
And there you have a link to download the doc.
