 # manjaro-package-mirror
 Docker container which mirrors manjaro packages and serves them via nginx
+
+This image is based on the alpine image and uses rsync to synchronize the packages and nginx to deliver them
+
+## Supported Architectures
+The image is built for the **amd64** and **arm64** platform and is available in the **DockerHub** and the **Github Container Registry** respectively.
+
+## Parameters
+A container can be started with various parameters to make changes to the default configuration, expose ports, and persist data. For example, `-p 8080:80` would expose port 80 inside the container for access from outside via port 8080. The following parameters are available for this image:
+
+| Parameter                                                            | Function                                                    |
+| -------------------------------------------------------------------- | ----------------------------------------------------------- |
+| `-p 8080:80`                                                         | Binds container port 80 to host port 8080                   |
+| `-v /path/to/storage:/srv/http/manjaro`                              | Persists the package repository data under /path/to/storage |
+| `-e SOURCE_MIRROR=rsync://mirrorservice.org/repo.manjaro.org/repos/` | Allows to use another mirror for synchronization            |
+| `-e SLEEP=6h`                                                        | Adjusts the pause time between synchronizations             |
+
+## Usage
+The container can be started either with `docker run` or `docker-compose`
+
+**Please make sure to choose a suitable directory for persistence before running the container and replace the placeholder "/path/to/storage" chosen here with it.**
+
+### docker-compose (recommended)
+````yaml
+---
+version: "3.4"
+services:
+  manjaro-mirror:
+    container_name: manjaro-mirror
+    image: ghcr.io/twiese99/manjaro-package-mirror
+    volumes:
+      - /path/to/storage:/srv/http/manjaro
+    ports:
+      - 8080:80
+    restart: unless-stopped
+````
+
+### docker run
+````bash
+docker run -d \
+  --name=manjaro-mirror \
+  -p 8080:80 \
+  -v /path/to/storage:/srv/http/manjaro \
+  --restart unless-stopped \
+  ghcr.io/twiese99/manjaro-package-mirror
