-# Rsync - Docker mod for openssh-server
+# cloudflare_real-ip - Docker mod for SWAG
 
-This mod adds rsync to openssh-server, to be installed/updated during container start.
+This mod adds a startup scipt that gets the IP's from Cloudflares edge servers, and formats them in a format Nginx can use with `set_real_ip_from`.
 
-In openssh-server docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:openssh-server-rsync`
+It reads this [list for IPv4](https://www.cloudflare.com/ips-v4), and this [list for IPV6](https://www.cloudflare.com/ips-v6).
 
-If adding multiple mods, enter them in an array separated by `|`, such as `DOCKER_MODS=linuxserver/mods:openssh-server-rsync|linuxserver/mods:openssh-server-mod2`
+In SWAG docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:swag-cloudflare-real-ip`
 
-# Mod creation instructions
+If adding multiple mods, enter them in an array separated by `|`, such as `DOCKER_MODS=linuxserver/mods:swag-cloudflare-real-ip|linuxserver/mods:swag-f2bdiscord`
 
-* Fork the repo, create a new branch based on the branch `template`.
-* Edit the `Dockerfile` for the mod. `Dockerfile.complex` is only an example and included for reference; it should be deleted when done.
-* Inspect the `root` folder contents. Edit, add and remove as necessary.
-* Edit this readme with pertinent info, delete these instructions.
-* Finally edit the `.github/workflows/BuildImage.yml`. Customize the build branch, and the vars for `BASEIMAGE` and `MODNAME`.
-* Ask the team to create a new branch named `<baseimagename>-<modname>`. Baseimage should be the name of the image the mod will be applied to. The new branch will be based on the `template` branch.
-* Submit PR against the branch created by the team.
+## Mod usage instructions
+
+The file gets placed in your persistant data, at `/config/nginx/cf_real-ip.conf`
+
+To enable nginx to read the ips from this file, you need the following in your nginx.conf:
+
+```nginx
+real_ip_header X-Forwarded-For;
+real_ip_recursive on;
+include /config/nginx/cf_real-ip.conf;
+```
+
+I also recommend including your docker-network as a valid ip `set_real_ip_from 172.17.0.0/16;` in the snippet above.
