In this repo's main README and in the output ofupdate-ngxblocker -h I did not find a description of exactly what the update-ngxblocker script does.

I would like to think that it updates the files in the bots directory (e.g. /etc/nginx/bots.d)and nothing else. Is that the case?

Whatever it does I suggest adding a description exactly what it does in readmes and the-h output.

Thank you for nginx-ultimate-bad-bot-blocker!
