+# GitHub Hop
+
+By [ajanlab](https://github.com/ajanlab)
+
+Select any text → instantly jump to its GitHub repo homepage.
+
+## Features
+
+- **owner/repo** (e.g. `facebook/react`) → instant jump, zero latency
+- **Project name** (e.g. `lodash`) → resolves via GitHub Search API to the best matching repo
+- **Author name** (e.g. `@ajanlab`) → auto-strip `@`, search GitHub
+- **Fallback** → API failure / rate limit / timeout → gracefully degrades to GitHub search
+
+## Requirements
+
+- PopClip 4631 (2023 or later)
+- macOS 10.15+
+- Internet connection (for API resolution and browser open)
+
+## Usage
+
+Select any text in any app, then click the GitHub icon in PopClip's toolbar.
+
+## Changelog
+
+### 1.0.0 (2026-07-14)
+- Initial release
+- owner/repo format → direct jump
+- Project name → GitHub Search API resolution with smart matching
+- @username → auto-strip and search
+- Transparent fallback to GitHub search page on any API failure
