+
+### Build the Image
+
+```bash
+docker build -t mdhost .
+```
+
+### Run with Docker
+
+The `data` and `posts` directories are designed to be bind-mounted from the host filesystem for persistence:
+
+```bash
+# Create host directories for persistent data
+mkdir -p ~/mdhost-data ~/mdhost-posts
+
+# Run the container with bind mounts
+docker run -d \
+  --name mdhost \
+  -p 8080:8080 \
+  -v ~/mdhost-posts:/posts \
+  -v ~/mdhost-data:/data \
+  mdhost
+```
+
+The application will be available at `http://localhost:8080`.
+
+- **`/posts`** - Markdown files are stored here (bind-mounted from host)
+- **`/data`** - Metadata (users, sessions, file metadata) is stored here as `data.json` (bind-mounted from host)
+
+### Docker Compose
+
+Create a `docker-compose.yml`:
+
+```yaml
+version: '3.8'
+services:
+  mdhost:
+    build: .
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./posts:/posts
+      - ./data:/data
+    restart: unless-stopped
+```
+
+Then run:
+
+```bash
+docker compose up -d
+```
+
