"Interacts with external caches, reverse proxies, and CDNs to remove content from their caches as content changes, while keeping unchanged content cached forever."

Interacts with external caches, reverse proxies, and CDNs to remove content from their caches as content changes, while keeping unchanged content cached forever.

We, the mentoring team, are triaging issues for first time contributors at DrupalCon Lille and I think this is a good issue for the contribution day.
We are reserving this issue so please don't work on this issue if you are not at DrupalCon Lille. You can continue the work when the event is over.

I'm working on this as a part DrupalCon Lille

Could we make this even easier for a non-technical people by saying:

The purge module, by clearing external caches, ensures quick and accurate updates to websites, making them faster, more reliable, and ready for heavy traffic.
