 ### Setup
 
 You can disable default mappings with
+
 ```vim
 " let g:nvim_tree_disable_keybindings=1
 ```
+
 But you won't be able to map any keys from the setup with nvim_tree_bindings. Use with caution.
 
 You can use only your mappings with
+
 ```vim
 let g:nvim_tree_disable_default_keybindings = 1
 ```
 
 You can define your own keymaps with this syntax:

 ```vim

 Notes:

 - `key` can be either a string or a table of strings
 - `mode` is `n` by default if you don't specify it
 - `cb` is the command that will be called when the keymap is triggered
