This would be a topic in a progress report that would outline what the project is about without going into details. I'm looking for something that means like 'Refresher' but sounds more professional.
Consider the term precis (or précis)
a summary of the essentials of a text; abstract
[from Collins English Dictionary]
- apercu (also aperçu, but some would not consider this English)
Compendium Conspectus Synopsis
Are you talking about an abstract? http://en.wikipedia.org/wiki/Abstract_(summary)
I think you can use the term survey:
A gathering of a sample of data or opinions considered to be representative of a whole.
A presentation of the substance of a body of material in a condensed form or by reducing it to its main points.
A brief statement that presents the main points in a concise form; "he gave a summary of the conclusions"
Outline - A general description or plan showing the essential features of something but not the detail.

I recommend "a brief". As a noun, it means a short summary, and it's common in legal discussions.
