-# rsyncd
-
-Simple rsync server running in a Docker container.
-
-Image: `harbor.lan/tools/rsyncd:latest`
-
-## Usage modes
-
-### 1. Custom config (mount rsyncd.conf)
-
-If `/etc/rsyncd.conf` is mounted, the container uses it as-is — no env vars needed.
-
-```yaml
-services:
-  rsyncd:
-    image: harbor.lan/tools/rsyncd:latest
-    ports:
-      - "873:873"
-    volumes:
-      - ./rsyncd.conf:/etc/rsyncd.conf:ro
-      - /srv/backup:/data
-```
-
-### 2. Multiple modules via env vars
-
-Modules are defined via `MODULE_1_*`, `MODULE_2_*`, `MODULE_3_*` etc. — add as many as needed, as long as the numbering is consecutive.
-
-```yaml
-services:
-  rsyncd:
-    image: harbor.lan/tools/rsyncd:latest
-    ports:
-      - "873:873"
-    environment:
-      - ALLOW=10.0.0.0/8
-      - MODULE_1_NAME=backup
-      - MODULE_1_PATH=/data/backup
-      - MODULE_2_NAME=media
-      - MODULE_2_PATH=/data/media
-      - MODULE_2_ALLOW=192.168.1.0/24
-    volumes:
-      - /srv/backup:/data/backup
-      - /srv/media:/data/media
-```
-
-### 3. Single module (simple)
-
-```yaml
-services:
-  rsyncd:
-    image: harbor.lan/tools/rsyncd:latest
-    ports:
-      - "873:873"
-    environment:
-      - VOLUME=backup
-      - ALLOW=10.0.0.0/8
-      - OWNER=1000
-      - GROUP=1000
-    volumes:
-      - /srv/backup:/volume
-```
-
-## Environment variables
-
-| Variable | Default | Description |
-|---|---|---|
-| `VOLUME` | `volume` | Module name (single-module mode) |
-| `ALLOW` | `192.168.0.0/16 172.16.0.0/12` | Allowed IP ranges (global default) |
-| `OWNER` | `nobody` | UID for created files |
-| `GROUP` | `nogroup` | GID for created files |
-| `MODULE_x_NAME` | — | Module name (multi-module mode) |
-| `MODULE_x_PATH` | `/volume_x` | Path for module x |
-| `MODULE_x_ALLOW` | `$ALLOW` | Allowed IPs for module x |
