My entire workflow is driven in the spirit of Vim.

Vim

I have two sets of configurations available for Neovim. One is written entirely
in VimScript. The other, is the one that I am currently
using written in Lua.

I always use the latest Nightly build, so some features may not work if you
install previous builds/stable releases and intend to use my configuration.

Make sure that you have Git installed.

Lua

Packer.nvim for plugin management.

VimScript

To install in Arch :

sudo pacman -S neovim

I would recommend the following plugin managers:
Personally, I used Vim-Plug.

1. Vim-Plug

• To install in a Windows machine using powershell.

iwr -useb https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim |`
ni "$(@($env:XDG_DATA_HOME, $env:LOCALAPPDATA)[$null -eq $env:XDG_DATA_HOME])/nvim-data/site/autoload/plug.vim" -Force

• To install in an Unix environment.

sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'

1. Vundle

• To install in any environment:

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
