-# go-github-dashboard
+# Go GitHub Dashboard
+
+A pure Go command-line application that generates a static GitHub dashboard by aggregating repository data from GitHub API and RSS feeds.
+
+## Features
+
+- Generate a comprehensive dashboard for any GitHub user or organization
+- View open pull requests, issues, and recent discussions for each repository
+- Clean, responsive UI with collapsible sections (no JavaScript required)
+- Hybrid approach using both GitHub API and RSS feeds for efficient data collection
+- Intelligent caching to reduce API calls and handle rate limits
+- Fully static output that can be deployed to any static hosting service
+
+## Installation
+
+### Using Go
+
+```bash
+go install github.com/yourusername/go-github-dashboard/cmd/go-github-dashboard@latest
+```
+
+### From Source
+
+```bash
+git clone https://github.com/yourusername/go-github-dashboard.git
+cd go-github-dashboard
+go build ./cmd/go-github-dashboard
+```
+
+## Usage
+
+```bash
+# Generate dashboard for a user
+go-github-dashboard generate --user octocat --output ./dashboard
+
+# Generate dashboard for an organization
+go-github-dashboard generate --org kubernetes --output ./k8s-dashboard
+
+# Use with authentication token (recommended for large organizations)
+go-github-dashboard generate --user developername --token $GITHUB_TOKEN --output ./my-dashboard
+
+# Specify cache duration
+go-github-dashboard generate --user octocat --cache-ttl 2h --output ./dashboard
+
+# Show version information
+go-github-dashboard version
+```
+
+### Command-line Options
+
+- `--user` or `-u`: GitHub username to generate dashboard for
+- `--org` or `-o`: GitHub organization to generate dashboard for
+- `--output` or `-d`: Output directory for the dashboard (default: `./dashboard`)
+- `--token` or `-t`: GitHub API token (optional, increases rate limits)
+- `--cache-dir`: Directory for caching API responses (default: `./.cache`)
+- `--cache-ttl`: Cache time-to-live duration (default: `1h`)
+- `--verbose` or `-v`: Enable verbose output
+
+### Environment Variables
+
+You can also set configuration using environment variables:
+
+- `GITHUB_DASHBOARD_USER`: GitHub username
+- `GITHUB_DASHBOARD_ORG`: GitHub organization
+- `GITHUB_DASHBOARD_OUTPUT`: Output directory
+- `GITHUB_DASHBOARD_TOKEN` or `GITHUB_TOKEN`: GitHub API token
+- `GITHUB_DASHBOARD_CACHE_DIR`: Cache directory
+- `GITHUB_DASHBOARD_CACHE_TTL`: Cache TTL duration
+- `GITHUB_DASHBOARD_VERBOSE`: Enable verbose output (set to `true`)
+
+## Output Structure
+
+The generated dashboard follows this structure:
+
+```
+output/
+├── index.html            # Main HTML dashboard
+├── style.css             # CSS styling
+├── README.md             # Dashboard information
+├── repositories/         # Directory containing markdown files
+│   ├── repo1.md          # Markdown version of repository data
+│   ├── repo1.html        # HTML version of repository data
+│   ├── repo2.md
+│   ├── repo2.html
+│   └── ...
+```
+
+## Development
+
+The project is structured as follows:
+
+```

+│   └── go-github-dashboard/
+│       └── main.go       # Application entry point

+
+## Key Features
+
+- **Concurrent Repository Processing**: Uses Go's concurrency features to fetch and process multiple repositories in parallel
+- **Intelligent Data Sourcing**: Prioritizes RSS feeds to avoid API rate limits, falling back to the GitHub API when needed
+- **Resilient API Handling**: Implements retries, timeouts, and graceful error handling for network requests
+- **Efficient Caching**: Stores API responses to reduce duplicate requests and speed up subsequent runs
+- **Pure Go Implementation**: Uses only Go standard library and well-maintained third-party packages
+- **No JavaScript Requirement**: Dashboard uses CSS-only techniques for interactivity (collapsible sections)
+- **Clean Architecture**: Separation of concerns with distinct packages for different responsibilities
+
+## Example Dashboard
+
+Once generated, the dashboard presents:
+
+- An overview of all repositories with key metrics
+- Expandable sections for each repository showing:
+  - Open pull requests with author and label information
+  - Open issues organized by priority and label
+  - Recent discussions categorized by topic
+- Responsive design that works on both desktop and mobile browsers
+- Both HTML and Markdown versions of all content
