Dear all is not an appropriate subject header. "Documents for Implementation Project" would have been more appropriate.
Renan named a few, and you'll find a lot more information if you do a seach on this site and elsewhere on the web. Also look for a "Roadmap", since the documents needed during an implementation project vary according to where you are on that roadmap. They'll start as an overview of the project, and get more detailed as time evolves, and the last ones are usually the configuration notes and the user's manual.
