 ## SSL Passthrough
 
 SSL Passthrough will allow you to proxy a server without [SSL termination](https://en.wikipedia.org/wiki/TLS_termination_proxy). This means the SSL encryption of the server will be passed right through the proxy, retaining the original certificate.

+## Customising logrotate settings
+
+By default, NPM rotates the access- and error logs weekly and keeps 4 and 10 log files respectively.
+Depending on the usage, this can lead to large log files, especially access logs.
+You can customise the logrotate configuration through a mount (if your custom config is `logrotate.custom`):
+
+```yml
+  volumes:
+    ...
+    - ./logrotate.custom:/etc/logrotate.d/nginx-proxy-manager
+```
+
+For reference, the default configuration can be found [here](https://github.com/NginxProxyManager/nginx-proxy-manager/blob/develop/docker/rootfs/etc/logrotate.d/nginx-proxy-manager).
