Extracting High level information on MECM infrastructure. Best Method

Hi

I am working with a customer performing a health check of their large MECM 2006 environment in regards to vulnerabilities and deployment of software updates to their devices.

As part of this I want to provide a general high level summary of the infrastructure such as how many MPs, DPs, SQL version.

I know I can get this information from the GUI via the System status, site status component status but would prefer to extract into a format I can put into a document.

I assume PowerShell might help here, is anyone able to advise where best I can start?

Thanks
