-## 🚀 Quick Start

+## 🚀 Deployment
+
+### Prerequisites
+
+- A running [Immich](https://immich.app/) server
+- An Immich API key (see below)
+- Docker and Docker Compose (recommended) — or Node.js 18+ for running from source
 
 ### 1. Get your Immich API Key
 
 1. Open your Immich web interface
 2. Click your profile picture → **Account Settings** → **API Keys**
 3. Create a new key with `asset.read` and `album.read` permissions
+4. Copy the key — you'll need it for the next step

+### 4. Run from Source (development)
+
+```bash
+git clone https://gitea.hideawaygaming.com.au/jessikitty/frambe.git
+cd frambe
+npm install
+```
+
+Create a `.env` file from the example:
+
+```bash
+cp .env.example .env
+```
+
+Edit `.env` with your Immich URL and API key, then start the server:
+
+```bash
+npm start
+```
+
+Frambe will be available at `http://localhost:3000`.
+
+### Port Mapping
+
+The internal server runs on port **3000**. The Docker Compose config maps this to external port **3030** by default. You can change this in `docker-compose.yml`:
+
+```yaml
+ports:
+  - "8080:3000"    # Access Frambe on port 8080 instead
+```

+
+## 🔄 Upgrading
+
+### Docker Compose (recommended)
+
+```bash
+cd frambe
+git pull
+docker compose build
+docker compose up -d
+```
+
+Your configuration in `docker-compose.yml` is preserved — only the application code is rebuilt.
+
+### Docker Run
+
+```bash
+cd frambe
+git pull
+docker stop frambe
+docker rm frambe
+docker build -t frambe .
+docker run -d \
+  --name frambe \
+  -p 3030:3000 \
+  -e IMMICH_URL=http://your-immich-server:2283 \
+  -e IMMICH_API_KEY=your-api-key \
+  --restart unless-stopped \
+  frambe
+```
+
+### From Source
+
+```bash
+cd frambe
+git pull
+npm install
+npm start
+```
+
+### Switching to a Specific Version
+
+Frambe uses git tags for releases. To pin to a specific version:
+
+```bash
+git fetch --tags
+git checkout v1.4.0        # Replace with desired version
+docker compose build && docker compose up -d
+```
+
+To switch back to the latest:
+
+```bash
+git checkout main
+git pull
+docker compose build && docker compose up -d
+```
+
+### Upgrade Notes
+
+- **All upgrades are non-destructive** — Frambe stores no persistent data on disk. All configuration is via environment variables.
+- **No database migrations** — there is no database. Session tokens are in-memory and will reset on restart (users simply log in again).
+- **Check the changelog below** before upgrading major versions for any new required environment variables.

+
+The Node.js backend acts as a secure proxy — your Immich API key never reaches the browser. The frontend periodically polls the backend for new photos so albums stay up to date without restarting.
