Neovim is a project that seeks to aggressively refactor Vim in order to:

- Simplify maintenance and encourage [contributions](CONTRIBUTING.md)
- Split the work between multiple developers
- Enable [advanced UIs] without modifications to the core
- Maximize [extensibility](https://github.com/neovim/neovim/wiki/Plugin-UI-architecture)

See [the wiki](https://github.com/neovim/neovim/wiki/Introduction) and [Roadmap]
for more information.
