```

Activate your virtual environment.

# Activate virtual environment

Configure environment variables.

# Copy environment variable template
cp .env.sample .env

# Edit .env file, configure:
# 1. Database connection info (DATABASE_NAME, DATABASE_USERNAME, DATABASE_PASSWORD)
# 2. At least one LLM configuration (e.g., Azure OpenAI, Qwen, Doubao, or Moonshot)

Select your LLM.

# Edit core/common/container.py file
# Find the llm registration section, replace with any of the following models (Qwen by default):
# - QwenLlm: Qwen
# - AzureLlm: Azure OpenAI
# - DoubaoLlm: Doubao
# - MoonshotLlm: Moonshot

# Example: Using Azure OpenAI
from core.llm.azure_open_ai import AzureLlm
# ...
llm = providers.Singleton(AzureLlm)

Start PostgreSQL database.

# Method 1: If PostgreSQL is installed locally
# Simply start your local PostgreSQL service

# Method 2: Using Docker (example)
docker run -d --name local-postgres \
  -e POSTGRES_DB=your_database_name \
  -e POSTGRES_USER=your_username \
  -e POSTGRES_PASSWORD=your_password \
  -p 5432:5432 \
  postgres

# Note: Ensure database connection info matches the configuration in your .env file

Initialize the database.

# Create a new version and generate a migration file in alembic/versions
alembic revision --autogenerate -m "initial migration"

# Preview SQL to be executed:
alembic upgrade head --sql

# If preview looks good, execute migration
alembic upgrade head

Start the service.

python -m uvicorn main:app --host 0.0.0.0 --port 8000
