+# XVN Has Been Renamed to ANVS
+
+⚠️ **IMPORTANT NOTICE**: This project has been renamed to **anvs** (Automatic Node Version Switcher)
+
+## Why the Rename?
+
+- **Better Name**: "Automatic Node Version Switcher" is more descriptive
+- **Unnamespaced Package**: `anvs` is available without namespace (vs `@olvrcc/xvn`)
+- **Clearer Purpose**: Name immediately communicates what the tool does
+- **Tribute to avn**: Pays homage to the original project while being distinct
+
+## What's Changing?
+
+| Old (xvn)                | New (anvs)               |
+|--------------------------|--------------------------|
+| `@olvrcc/xvn`            | `anvs`                   |
+| `xvn` binary             | `anvs` binary            |
+| `~/.xvn/` directory      | `~/.anvs/` directory     |
+| `~/.xvnrc` config        | `~/.anvsrc` config       |
+| `.xvn.yaml` project file | `.anvs.yaml` project file|
+
+## Migration Instructions
+
+### For New Users
+Install the new package directly:
+```bash
+npm install -g anvs
+anvs setup
+```
+
+### For Existing XVN Users
+
+1. **Backup your config** (optional but recommended):
+   ```bash
+   cp ~/.xvnrc ~/.xvnrc.backup
+   ```
+
+2. **Uninstall xvn**:
+   ```bash
+   xvn uninstall
+   # or manually: npm uninstall -g @olvrcc/xvn
+   ```
+
+3. **Install anvs**:
+   ```bash
+   npm install -g anvs
+   anvs setup
+   ```
+
+4. **Migrate config** (if you had custom settings):
+   - Copy settings from `~/.xvnrc.backup` to `~/.anvsrc`
+   - Rename project-level `.xvn.yaml` to `.anvs.yaml`
+
+## Timeline
+
+- **v1.7.0** (Current): Final xvn release with deprecation notice
+- **v2.0.0**: New `anvs` package published (coming soon)
+- **Ongoing**: Both packages will coexist during transition period
+
+## Support
+
+- New package: https://github.com/olvrcc/anvs
+- Migration help: https://github.com/olvrcc/anvs/issues
+- Full migration guide: [Link will be added when published]
+
+## Will XVN Stop Working?
+
+**No!** Your current `xvn` installation will continue to work indefinitely. However:
+- No new features will be added to `xvn`
+- Bug fixes and updates will only go to `anvs`
+- We recommend migrating when convenient
+
+---
+
+*Thank you for using xvn! We look forward to seeing you on anvs.*
