 - It’s been around forever, and frankly, probably always will be.
 
 Therefore, I decided to create this repository. There are several versions:
-- [v0.1.0](): written in VimL, a single file only.
-- [v0.1.1](): written in VimL, consist of mutliple files.
-- [v0.2.0](): started this version, switch from VimL to Lua. For the reason, you may to check [neovim's official wiki](https://github.com/neovim/neovim/wiki/FAQ#why-embed-lua-instead-of-x). Follow [KISS principle](https://en.wikipedia.org/wiki/KISS_principle), this version uses the least plugins as possible. It's more like a skeleton, users can add more plugins and LSP.
