 # Introduction

-This repo hosts my Nvim configuration for all the platforms I am using (Linux,
-Windows and macOS). `init.vim` is the config entry point for terminal Nvim,
-and `ginit.vim` is the additional config file for GUI client of Nvim (I am
-using [neovim-qt](https://github.com/equalsraf/neovim-qt) for now on Windows).

-My configurations are heavily documented to make it as clear as possible. While

-Good configurations are personal. Everyone should have his or her unique config
-file. You are encouraged to copy from this repo the part you feel useful and
