 # pictshare-browse
 
+## Running in Production with Docker Compose
+
+This project is designed to run as a containerized Node.js app that serves a gallery of images uploaded to PictShare. It reads a CSV file from a mounted volume and displays the images in a web gallery.
+
+### 1. Build the Docker Image
+
+Clone this repository to your server, then build the image:
+
+```bash
+docker compose build
+```
+
+### 2. Start the Service
+
+```bash
+docker compose up -d
+```
+
+This will start the service in the background. The app will be available on port 3000.
+
+### 3. Mount the PictShare Uploads
+
++Make sure your pictshare uploads directory (with the `sha1.csv` file) is available in a local folder. The example `docker-compose.yml` now mounts `./pictshare-data` from your host to `/uploads` in the container (read-only).
+
+Example `docker-compose.yml`:
+
+```yaml
+version: '3.8'
+services:
+  image-api:
+    container_name: pictshare-images
+    build: .
+    restart: unless-stopped
+    ports:
+      - "3000:3000"
+    volumes:
+      - ./pictshare-data:/uploads:ro
+```
+
+Place your `sha1.csv` and images inside the `./pictshare-data` directory in your project root. The container will read from this folder at startup.
+
+### 4. Updating the App
+
+If you make changes to the code, rebuild the image:
+
+```bash
+docker compose build
+docker compose up -d
+```
+
+---
+
+For development, you can still run locally with:
+
+```bash
+npm install
+npm start
+```
+
+---
+
+If you have questions or need help with your production setup, open an issue or ask for support.
