+}
+```
+
+**Response:**
+```
+200 OK
+```
+
+### Delta Sync
+
+**`POST /sync/delta`**
+
+Sync only changed data since your last sync. Much faster than full sync.
+
+**Request Body:**
+```json
+{
+  "lastSyncTime": "2024-01-15T10:00:00.000Z",
+  "gyms": [...],
+  "problems": [...],
+  "sessions": [...],
+  "attempts": [...],
+  "deletedItems": [...]
+}
+```
+
+Include only items modified after `lastSyncTime`. The server merges your changes with its data using last-write-wins based on `updatedAt` timestamps.
+
+**Response:**
+```json
+{
+  "serverTime": "2024-01-15T10:30:00.000Z",
+  "gyms": [...],
+  "problems": [...],
+  "sessions": [...],
+  "attempts": [...],
+  "deletedItems": [...]
+}
+```
+
+Returns only server items modified after your `lastSyncTime`. Save `serverTime` as your new `lastSyncTime` for the next delta sync.
+
+### Image Upload
+
+**`POST /images/upload?filename={name}`**
+
+Upload an image file.
+
+**Query Parameters:**
+- `filename`: Image filename (e.g., `problem_abc123_0.jpg`)
+
+**Request Body:**
+Binary image data (JPEG, PNG, GIF, or WebP)
+
+**Response:**
+```
+200 OK
+```
+
+### Image Download
+
+**`GET /images/download?filename={name}`**
+
+Download an image file.
+
+**Query Parameters:**
+- `filename`: Image filename
+
+**Response:**
+Binary image data with appropriate `Content-Type` header.
+
+Returns `404 Not Found` if the image doesn't exist.
+
+## Notes
+
+- All timestamps are ISO 8601 format with milliseconds
+- Active sessions (status `active`) are excluded from sync
+- Images are stored separately and referenced by filename
+- The server stores everything in a single `ascently.json` file
+- No versioning or history - last write wins

+- `GET /health` - Health check
+- `GET /sync` - Download full dataset
+- `POST /sync` - Upload full dataset
+- `POST /sync/delta` - Sync only changes (recommended)

 ## Getting Started
 
-The easiest way to get started is with the [Quick Start guide](/sync/quick-start/) using Docker Compose.
+Check out the [Quick Start guide](/sync/quick-start/) to get your server running with Docker Compose.
 
 You'll need:
 - Docker and Docker Compose
 - A secure authentication token
 - A place to store your data
 
-The server will be available at `http://localhost:8080` by default. Configure your clients with your server URL and auth token to start syncing.
+The server will be available at `http://localhost:8080` by default. Configure your Ascently apps with your server URL and auth token to start syncing.
+
+## How Sync Works
+
+1. **First sync**: Client uploads or downloads full dataset
+2. **Subsequent syncs**: Client uses delta sync to only transfer changed data
+3. **Conflicts**: Resolved automatically using timestamps (newer wins)
+4. **Images**: Synced automatically with problem data
+
+Active sessions are excluded from sync until completed.

 ## Prerequisites
 
@@ -12,50 +12,158 @@ Get your Ascently sync server up and running using Docker Compose.
 
 ## Setup
 
-1. Create a `.env` file with your configuration:
+1. Create a `docker-compose.yml` file:
 
-```env
-IMAGE=git.atri.dad/atridad/ascently-sync:latest
-APP_PORT=8080
-AUTH_TOKEN=your-super-secret-token
-DATA_FILE=/data/ascently.json
-IMAGES_DIR=/data/images
-ROOT_DIR=./ascently-data
+```yaml
+version: '3.8'
+
+services:
+  ascently-sync:
+    image: git.atri.dad/atridad/ascently-sync:latest
+    ports:
+      - "8080:8080"
+    environment:
+      - AUTH_TOKEN=${AUTH_TOKEN}
+      - DATA_FILE=/data/ascently.json
+      - IMAGES_DIR=/data/images
+    volumes:
+      - ./ascently-data:/data
+    restart: unless-stopped
 ```
 
-Set `AUTH_TOKEN` to a long, random string. `ROOT_DIR` is where the server will store its data on your machine.
+2. Create a `.env` file in the same directory:
 
-2. Use the provided `docker-compose.yml` in the `sync/` directory:
+```env
+AUTH_TOKEN=your-super-secret-token-here
+```
+
+Replace `your-super-secret-token-here` with a secure random token (see below).
+
+3. Start the server:
 
 ```bash
-cd sync/
 docker-compose up -d
 ```
 
 The server will be available at `http://localhost:8080`.
 
-## Configure Your Clients
+## Generate a Secure Token
 
-Configure your Ascently apps with:
-- **Server URL**: `http://your-server-ip:8080` (or your domain)
-- **Auth Token**: The token from your `.env` file
-
-Enable sync and perform your first sync to start synchronizing data across devices.
-
-## Generating a Secure Token
-
-Generate a secure authentication token:
+Use this command to generate a secure authentication token:
 
 ```bash
-# On Linux/macOS
 openssl rand -base64 32
 ```
 
-Keep this token secure and don't share it publicly.
+Copy the output and paste it into your `.env` file as the `AUTH_TOKEN`.
 
-## Accessing Remotely
+Keep this token secret and don't commit it to version control.
 
-For remote access, you'll need to:
-- Set up port forwarding on your router (port 8080)
-- Use your public IP address or set up a domain name
-- Consider using HTTPS with a reverse proxy for security
+## Configure Your Apps
+
+Open Ascently on your iOS or Android device:
+
+1. Go to **Settings**
+2. Scroll to **Sync Configuration**
+3. Enter your **Server URL**: `http://your-server-ip:8080`
+4. Enter your **Auth Token**: (the token from your `.env` file)
+5. Tap **Test Connection** to verify it works
+6. Enable **Auto Sync**
+7. Tap **Sync Now** to perform your first sync
+
+Repeat this on all your devices to keep them in sync.
+
+## Verify It's Working
+
+Check the server logs:
+
+```bash
+docker-compose logs -f ascently-sync
+```
+
+You should see logs like:
+
+```
+Delta sync from 192.168.1.100: lastSyncTime=2024-01-15T10:00:00.000Z, gyms=1, problems=5, sessions=2, attempts=10, deletedItems=0
+```
+
+## Remote Access
+
+To access your server remotely:
+
+### Option 1: Port Forwarding
+
+1. Forward port 8080 on your router to your server
+2. Find your public IP address
+3. Use `http://your-public-ip:8080` as the server URL
+
+### Option 2: Domain Name (Recommended)
+
+1. Get a domain name and point it to your server
+2. Set up a reverse proxy (nginx, Caddy, Traefik)
+3. Enable HTTPS with Let's Encrypt
+4. Use `https://sync.yourdomain.com` as the server URL
+
+Example nginx config with HTTPS:
+
+```nginx
+server {
+    listen 443 ssl http2;
+    server_name sync.yourdomain.com;
+
+    ssl_certificate /etc/letsencrypt/live/sync.yourdomain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/sync.yourdomain.com/privkey.pem;
+
+    location / {
+        proxy_pass http://localhost:8080;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+## Updating
+
+Pull the latest image and restart:
+
+```bash
+docker-compose pull
+docker-compose up -d
+```
+
+Your data is stored in `./ascently-data` and persists across updates.
+
+## Troubleshooting
+
+### Connection Failed
+
+- Check the server is running: `docker-compose ps`
+- Verify the auth token matches on server and client
+- Check firewall settings and port forwarding
+- Test locally first with `http://localhost:8080`
+
+### Sync Errors
+
+- Check server logs: `docker-compose logs ascently-sync`
+- Verify your device has internet connection
+- Try disabling and re-enabling sync
+- Perform a manual sync from Settings
+
+### Data Location
+
+All data is stored in `./ascently-data/`:
+
+```
+ascently-data/
+├── ascently.json    # Your climb data
+└── images/          # Problem images
+```
+
+You can back this up or move it to another server.
+
+## Next Steps
+
+- Read the [API Reference](/sync/api-reference/) for advanced usage
+- Set up automated backups of your `ascently-data` directory
+- Configure HTTPS for secure remote access
+- Monitor server logs for sync activity
