-# Rsync - Docker mod for openssh-server
+# DBIP Docker mod for Nginx based images
 
-This mod adds rsync to openssh-server, to be installed/updated during container start.
+This mod downloads the `dbip-country-lite.mmdb` database under `/config/geoip2db`, the database is updated weekly.
 
-In openssh-server docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:openssh-server-rsync`
+**This mod should not be enabled together with the swag-maxmind mod.**
 
-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`
+Follow these steps to enable the dbip mod:
 
-# Mod creation instructions
+1. In the container's docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:swag-dbip`
+   
+   If adding multiple mods, enter them in an array separated by `|`, such as `DOCKER_MODS=linuxserver/mods:swag-dbip|linuxserver/mods:swag-mod2`
+2. Add the following line to `/config/nginx/nginx.conf` under the `http` section:
+   
+   ```nginx
+   include /config/nginx/dbip.conf;
+   ```
+3. Edit `/config/nginx/dbip.conf` and add countries to the blocklist / whitelist according to the comments, for example:
+   
+    ```nginx
+    map $geoip2_data_country_iso_code $geo-whitelist {
+        default no;
+        UK yes;
+    }
 
-* Fork the repo, create a new branch based on the branch `template`.
+    map $geoip2_data_country_iso_code $geo-blacklist {
-* Edit the `Dockerfile` for the mod. `Dockerfile.complex` is only an example and included for reference; it should be deleted when done.
+        default yes;
-* Inspect the `root` folder contents. Edit, add and remove as necessary.
+        US no;
-* Edit this readme with pertinent info, delete these instructions.
+    }
-* Finally edit the `.github/workflows/BuildImage.yml`. Customize the build branch, and the vars for `BASEIMAGE` and `MODNAME`.
+    ```
-* Ask the team to create a new branch named `<baseimagename>-<modname>`. Baseimage should be the name of the image the mod will be applied to. The new branch will be based on the `template` branch.
+4. Use the definitions in the following way:
-* Submit PR against the branch created by the team.
+   ```nginx
+    server {
+        listen 443 ssl;
+        listen [::]:443 ssl;
+
+        server_name some-app.*;
+        include /config/nginx/ssl.conf;
+        client_max_body_size 0;
+
+        if ($lan-ip = yes) { set $geo-whitelist yes; }
+        if ($geo-whitelist = no) { return 404; }
+
+        location / {
+    ```
+5. Recreate the container to apply the changes.
