 # Purpose
 
 There are many existing markdown rendering plugins in the Neovim ecosystem. However,
-most of these rely on syncing a separate browser window with the buffer. This is the
-correct way to do things to get full feature support, however I wanted something that
-worked completely inside of Neovim and made things look slightly "nicer".

 The closest one I found to this was [headlines.nvim](https://github.com/lukas-reineke/headlines.nvim),
-which is an awesome plugin that I took several ideas from. However it just didn't have
-quite what I was looking for. In particular I wanted something that would disappear completely
-when editing a file and quickly render some style when viewing the file. Hence this plugin.
