Web help to Sharepoint site

I've some basic project documentation (help). It is a index page with frames and a lot of html files with images. To make 开发者_运维知识库a better use i want to deploy it on Sharepoint site (with configured search).

Easiest way to do this its a iframe webpart, but it's not a good decision.

1. Put the help files under _layouts directory.

2. Use the Page Viewer WebPart to place each of this page in its individual SharePoint pages.

3. Crawl the SharePoint pages only.
