+You can replace original `geoip.dat` and `geosite.dat` with the ones from this repo and route only blocked traffic through the proxy.

+# GeoIP Categories
+
+- `geoip:ru-blocked-ips-all` - IP's and IP ranges blocked in Russia.
+- `geoip:ru-blocked-ips-directblock` - IP's blocked in Russia directly by address.
+- `geoip:ru-blocked-ips-noid2971` - IP's and IP ranges blocked in Russia excluding those blocked by 33а-5536/2019.
+
+# GeoSite Categories
+
+- `geosite:category-ru-blocked-domains` - domains and subdomains blocked in Russia.
+- `geosite:category-ru-blocked-zones` - only second-level domains blocked in Russia (even if only subdomain was blocked).
+
+# Automatic Update
+
+There is no universal recipe. Just download `geoip.dat` and `geosite.dat` from latest release daily and replace old files with the new ones. 
+You can find an example of how to get the latest files in the [`update.sh`](./update.sh). And please, for the love of all that is holy, **don't put** `curl -fsSL ... | bash` to your crontab, **it's not safe**.
