Disclaimer

This setup is based on KISS principle, probably some concepts may not be valid for everyone. Then feel free to take what you need but don't install anything without checking first!

This setup is not a Framework but it is the configuration I use to work on Linux, it can be used by default as it can be a start point to understand how Neovim is structured and maybe improve this config.

Thanks to:

• All the contributors who helped improve this setup with their reports and advices.

• All the authors of the sources mentioned above.

• The users of /r/Neovim subreddit for the support of the configuration.
