It's unusual to see the word "silently" used as a selling point these days. In headlines, it's almost always used in the context of some bad behavior and as such has taken on negative connotations for me. https://hn.algolia.com/?q=silently

I plugged the title of this post into a few online sentiment analysis tools and they both rated it as having negative sentiment. If the author sees this, you might want to swap it out for another word like "automatically" in the readme.
