╚══════════════════════════════════════════════════════════════════════╝

1. BUILD DOCKER IMAGE (Server)
   ─────────────────────────────────────────────────────────────────
   Prerequisites:
     • Docker installed (https://docs.docker.com/get-docker/)

   Build:
     $ ./build_docker.sh

     Or manually:
     $ docker build -t lablink-server:0.10.0 .
     $ docker tag lablink-server:0.10.0 lablink-server:latest

   Test:
     $ docker run -p 8000:8000 -p 8001:8001 lablink-server:0.10.0
     $ curl http://localhost:8000/health

   Save for distribution:
     $ docker save lablink-server:0.10.0 | gzip > lablink-server-0.10.0.tar.gz

   Size: ~250-350 MB compressed

2. BUILD CLIENT EXECUTABLE (GUI)
   ─────────────────────────────────────────────────────────────────
   Prerequisites:
     • Python 3.11+
     • PyInstaller: pip install pyinstaller
     • Client dependencies: cd client && pip install -r requirements.txt

   Build:
     $ cd client
     $ ./build_client.sh

     Or manually:
     $ cd client
     $ pyinstaller lablink.spec

   Output:
     Windows:  client/dist/LabLink.exe       (~95 MB)
     macOS:    client/dist/LabLink.app       (~110 MB)
     Linux:    client/dist/LabLink           (~88 MB)

   Test:
     $ ./dist/LabLink  (or LabLink.exe)
     Click "Connect to Server..."
     Enter: localhost:8000

3. USING DOCKER-COMPOSE (Recommended)
   ─────────────────────────────────────────────────────────────────
   Start server:
     $ docker-compose up -d

   View logs:
     $ docker-compose logs -f

   Stop server:
     $ docker-compose down

   Update:
     $ docker-compose pull
     $ docker-compose up -d

4. DISTRIBUTION PACKAGE
   ─────────────────────────────────────────────────────────────────
   Create a complete distribution:

   LabLink-v1.0.0/
   ├── Server/
   │   ├── lablink-server-0.10.0.tar.gz    (Docker image)
   │   ├── docker-compose.yml
   │   └── README.txt
   ├── Windows/
   │   ├── LabLink.exe
   │   └── README.txt
   ├── macOS/
   │   ├── LabLink.dmg
   │   └── README.txt
   └── Linux/
       ├── LabLink
       └── README.txt

5. VERIFICATION
   ─────────────────────────────────────────────────────────────────
   After building, test:
     • Server: curl http://localhost:8000/health
     • Client: Launch and connect to localhost
     • API Docs: http://localhost:8000/docs
