+INTRODUCTION                                            *lf-introduction*
+
+*lf.nvim* is a plugin written in Lua that allows you to use the
+*lf* <https://github.com/gokechan/lf> file manager inside of Neovim.
+
+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)
+2. *toggleterm.nvim* (https://github.com/akinsho/toggleterm.nvim)

+
+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.
