+# A simple tree for neovim written in lua
+
+## Notice
+
+This work is under development, do not try to use it, it does not work.
+
+I am working on this plugin to learn lua, become better with neovim api and create a **simple** file explorer with features i need.
+
+I really don't like any of the vim trees, they are all too complicated for their purpose. I do have my shell to do most commands.
+
+
+## Goals / Features
+
+- [] moving around the file structure like any basic tree
+- [] open file in current buffer or in split with FzF like bindings (CR, C-v, C-x)
+- [] add / delete file in directory
+- [] quickly find file in the directory structure
+- [] icons for files
+- [] simple git integration (color of file changing when staged/changed)
+
