This is a neovim plugin for the [`lf`](https://github.com/gokcehan/lf) file manager.
It is very similar to [`lf.vim`](https://github.com/ptzz/lf.vim), except for that this is written in Lua.
**NOTE**: This plugin uses [`toggleterm.nvim`](https://github.com/akinsho/toggleterm.nvim) and [`plenary.nvim`](https://github.com/nvim-lua/plenary.nvim)
**NOTE**: This plugin uses [`toggleterm.nvim`](https://github.com/akinsho/toggleterm.nvim).

`lf.nvim` is a plugin written in Lua that allows you to use the

There is a similar plugin `lf.vim` <https://github.com/ptzz/lf.vim> which
basically does the same thing, except that is is written in Vimscript.
Since this plugin uses the Neovim window API, Vim is not supported.
================================================================================
REQUIREMENTS *lf-requirements*
1. *Lf* (https://github.com/gokechan/lf)

INSTALLATION *lf-installation*
Requires lf to be installed. The installation instructions for lf can be
found here <https://github.com/gokcehan/lf#installation>.
A sample installation is given.
NOTE: Replacing |netrw| will not work correctly if the plugin is lazily loaded.
