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.

    Vim is Charityware.  You can use and copy it as much as you like, but you are
    encouraged to make a donation for needy children in Uganda.  Please see the
    kcc section of the vim docs or visit the ICCF web site, available at these URLs:

            http://iccf-holland.org/

    You can also sponsor the development of Vim.  Vim sponsors can vote for
    features.  The money goes to Uganda anyway.
