+## Running With Docker
+A new [Docker image](https://github.com/utkuufuk?tab=packages&repo_name=github-service) will be created upon each [release](https://github.com/utkuufuk/github-service/releases).
+

+    ```sh
+    echo $GITHUB_ACCESS_TOKEN | docker login ghcr.io -u GITHUB_USERNAME --password-stdin
+    ```
+
+2. Pull the latest Docker image:
+    ```sh
+    docker pull ghcr.io/utkuufuk/github-service/image:latest
+    ```
+
+3. Start a container:
+    ```sh
+    # server
+    docker run -d \
+        -p <PORT>:<PORT> \
+        --env-file </absolute/path/to/.env> \
+        --restart unless-stopped \
+        --name github-service \
+        ghcr.io/utkuufuk/github-service/image:latest
