 ## Notice
 
-This is under development, do not try to use it right now. The best you could do is wait or give me tips to work better with lua.
-
-I am working on this plugin to learn lua, learn 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.
+- This plugin is under development, it does not yet have all basic functionnalities required by an explorer.
+- I am working on this plugin to learn lua, learn 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 purposes and are kind of buggy. I have my shell to do most commands.
+- This plugin wont work on windows.
 
 ## Goals / Features
 
-### 0.1
-- [ ] moving around the file structure like any basic tree
+- [x] moving around the file structure like any basic tree
 - [x] open file in current buffer or in split with FzF like bindings (CR, C-v, C-x)
-
-### 0.2
 - [ ] add / delete file in directory
 - [ ] quickly find file in the directory structure
-
-### 0.3
 - [ ] icons for files
 - [ ] simple git integration (color of file changing when staged/changed)
