In every issue

Why it exists
One paragraph on the problem it solves and what it displaces. If we can't say that clearly, it isn't included.
Downloads, not stars
Recent and all-time downloads, and week-on-week growth where the registry reports it. Star counts are easy to buy.
Maturity flags
Version and licence, so you know what you'd be adopting.
