+## Features
+- Commands for moving, renaming, creating, deleting, or, duplicating files and
+more. 
+- Commands for copying the path or name of the current file in various formats.
+- Renaming commands notify the LSP, meaning references to the renamed file like
+`import` statements are updated (if the LSP supports it).
+- Lightweight plugin, no file management UI or file tree.
+- Various quality-of-life improvements like automatically keeping the extensions
+when no extension is given.
+- Fully written in lua and makes use of up-to-date nvim features `vim.ui.input`.
+This that for example you can get nicer input fields with normal mode support
+via plugins like [dressing.nvim](https://github.com/stevearc/dressing.nvim).
