 ## Features
 
-- TLS available
+- TLS is avaliable.
 - Can run behind a proxy by trusting a custom header (usually `X-Real-IP`) to figure out the source IP address.
 - IPv4 and IPv6.
 - Geolocation info including ASN. This feature is possible thanks to [maxmind](https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?lang=en) GeoLite2 databases. In order to use these databases, a license key is needed. Please visit Maxmind site for further instructions and get a free license.
-- High performance
-- Although a docker image is provided the executable can reload databases and/or SSL certificates by itself, `hup` signal is honored.
-- HTML with templates, text plain and JSON output.
+- High performance.
+- Self-contained server what can reload GeoLite2 databases and/or SSL certificates without stop/start. The `hup` signal is honored.
