🚀 Quick Start

1. Set your provider

# Google Gemini (free tier available — https://aistudio.google.com/apikey)
export MINT_PROVIDER=google-genai
export MINT_API_KEY=your_gemini_api_key

# OpenAI
export MINT_PROVIDER=openai
export MINT_API_KEY=sk-...

# Anthropic
export MINT_PROVIDER=anthropic
export MINT_API_KEY=sk-ant-...

# Local Ollama (no API key needed)
export MINT_PROVIDER=ollama
export MINT_BASE_URL=http://localhost:11434
export MINT_MODEL_NAME=llama2

2. Translate

mint --target ja "Good morning"
mint -t zh-TW "Good morning"

echo "The quick brown fox" | mint -t fr
cat document.txt | mint -t zh-TW

3. Smart language detection

export MINT_TARGET_LANG=en
mint "早安"             # Detects Chinese → translates to en
mint "Good mooorning"  # Detects English → corrects grammar & spelling

# Rotate across multiple targets
export MINT_TARGET_LANG=en,zh-TW,ja
mint "Hello"       # → zh-TW
mint "你好"        # → ja
mint "こんにちは"   # → en
