+# Yahoo Finance CLI
+
+A Python CLI for fetching comprehensive stock data from Yahoo Finance using yfinance.
+
+## Requirements
+
+- Python 3.11+
+- uv (for inline script dependencies)
+
+## Installing uv
+
+The script requires `uv` - an extremely fast Python package manager. Check if it's installed:
+
+```bash
+uv --version
+```
+
+If not installed, install it using one of these methods:
+
+### macOS / Linux
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+### macOS (Homebrew)
+```bash
+brew install uv
+```
+
+### Windows
+```powershell
+powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+### pip (any platform)
+```bash
+pip install uv
+```
+
+After installation, restart your terminal or run:
+```bash
+source ~/.bashrc  # or ~/.zshrc on macOS
+```
+
+## Installation
+
+The `yf` script uses PEP 723 inline script metadata - dependencies are auto-installed on first run.
+
+```bash
+# Make executable
+chmod +x /path/to/skills/yahoo-finance/yf
+
+# Optionally symlink to PATH for global access
+ln -sf /path/to/skills/yahoo-finance/yf /usr/local/bin/yf
+```
+
+First run will install dependencies (yfinance, rich) to uv's cache. Subsequent runs are instant.
+
+## Commands
+
+### Price (quick check)
+```bash
+yf AAPL              # shorthand for price
+yf price AAPL
+```

+
+### History

+```
+Ranges: 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max
+
+### Compare

+
+## Troubleshooting
+
+### "command not found: uv"
+Install uv using the instructions above.
+
+### Rate limiting / connection errors
+Yahoo Finance may rate limit excessive requests. Wait a few minutes and try again.
+
+### "No data" for a symbol
+- Verify the symbol exists: `yf search "company name"`
+- Some data (options, dividends) isn't available for all securities
+
+## Technical Notes
+
+- Uses PEP 723 inline script metadata for uv dependencies
+- Rich library provides colored, formatted tables
+- First run installs deps to uv cache (~5 seconds)
+- Subsequent runs are instant (cached environment)
+- Handles NaN/None values gracefully with fallbacks
