-### If using Cloudflare
+### If using Cloudflare / Reverse Proxy
 In order to get the real IP and not use the cloudflare Proxy IP for placing pixels, we filter those out. The cloudflare IPs are in src/utils/cloudflareip.js and used in src/utils/ip.js. If for some reason cloudflare ads more IPs to it, you can see them at https://www.cloudflare.com/ips/ and add them.
 If you use any other Reverse Proxy, you can define it's IPs there too.
 
+If USE\_XREALIP is set, we take the IP from the X-Real-Ip header without checking for cloudflare IPs. Use this if you have pixelplanet running behind nginx use the nginx set\_realip module to give us the client ip on the X-Real-Ip header. And be sure to also forward X-Forwarded-Port and set X-Forwarded-Proto.
+
 ### Auto-Start
 To have the canvas with all it's components autostart at systemstart,
 enable mysql, redis (and probably nginx if you use it) according to your system (`systemctl enable ...`)
