+A complete Python CLI package for Growth-Hacking-Kit that enables users to install and use the tool via `uvx` or `pip`.
+
+### Key Features
+
+1. **ASCII Art Banner**: Beautiful "Growth Hacking Kit" ASCII art displayed on init
+2. **Interactive Mode**: Prompts for project name, agent, and script type if not provided
+3. **Template Download**: Automatically downloads templates from GitHub releases
+4. **17 AI Agents Supported**: claude, cursor-agent, windsurf, gemini, copilot, qoder, qwen, opencode, codex, kilocode, auggie, roo, codebuddy, amp, shai, q, bob
+5. **Dual Script Support**: Both bash (sh) and PowerShell (ps) variants
+6. **Rich Terminal UI**: Progress indicators, tables, and formatted output
+7. **Version Management**: Automatically fetches latest release version
+

+
+## Installation Methods
+
+### Method 1: uvx (Recommended)
+
+```bash
+uvx --from git+https://github.com/agentii-ai/growth-hacking-kit.git growthkit init my-campaign
+```
+
+### Method 2: pip
+
+```bash
+pip install git+https://github.com/agentii-ai/growth-hacking-kit.git
+growthkit init my-campaign
+```
+
+### Method 3: Development
+
+```bash
+git clone https://github.com/agentii-ai/growth-hacking-kit.git
+cd growth-hacking-kit
+pip install -e .
+growthkit init my-campaign
+```
+
+---
+
+## Usage Examples
+
+### Interactive Mode
+
+```bash
+growthkit init
+```
+
+Prompts for:

+
+### Command-Line Mode
+
+```bash
+# Basic usage
+growthkit init my-campaign --agent claude --script sh
+
+# Short form
+growthkit init my-campaign -a cursor-agent -s ps
+
+# With specific version

+
+## Key Implementation Details
+
+### Template Download Logic
+
+1. Fetches latest version from GitHub API
+2. Constructs download URL: `https://github.com/agentii-ai/growth-hacking-kit/releases/download/{version}/spec-kit-template-{agent}-{script}-{version}.zip`
+3. Downloads ZIP file with progress indicator
+4. Extracts to target directory
+5. Renames extracted directory to match project name
+
+### Error Handling
+
+- 404 errors show available agents and script types
+- Network errors display clear error messages
+- Existing directory prompts for confirmation (unless --force)
+- Invalid agent/script choices show available options
+
+### User Experience
+
+- Rich terminal UI with colors and formatting
+- Progress spinners during download
+- Success panel with next steps
+- Interactive prompts with defaults
+- Table display of available agents
