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

Simplify maintenance and encourage contributions
Split the work between multiple developers
Enable advanced UIs without modifications to the core
Maximize extensibility

See the Introduction wiki page and Roadmap for more information.

#Install from package

Pre-built packages for Windows, macOS, and Linux are found on the Releases page.

Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Void Linux, Gentoo, and more!

#Install from source

See BUILD.md and supported platforms for details.

The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.

make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install

To install to a non-default location:

make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install

CMake hints for inspecting the build:

cmake --build build --target help lists all build targets.
build/CMakeCache.txt (or cmake -LAH build/) contains the resolved values of all CMake variables.
build/compile_commands.json shows the full compiler invocations for each translation unit.

#Transitioning from Vim
