+# Setup proxy for certain indexers
+
+It's not recommend to run the Starr apps though a VPN,  what can happen is that the Starr apps doesn't update the posters or metadata or you can't add new movies/tv shows, it doesn't need to happen right away. but sooner or later it can and probably will happen.
+
+Just run VPN on the apps that actually need it, like your torrent client, and perhaps in some cases certain indexers because of region/isp restriction.
+
+!!! warning
+    Please check the indexers rules if you're allowed to use a VPN/Proxy to access their site, being that VPN services often use shared IP it could be recognized as account sharing.
+
+    This isn't the same as the tracker, the API/Website scraping happens on the actual site and some indexers don't allow VPN usage on their site.
+
+In this guide i will try to explain how to setup Prowlarr to use your vpn from your torrent client.
