+# eza-preview.yazi
+
+[Yazi](https://github.com/sxyazi/yazi) plugin to preview directories using [eza](https://github.com/eza-community/eza), can be switched between list and tree modes.
+
+List mode:
+![list.png](list.png)
+
+Tree mode:
+![tree.png](tree.png)
+
+## Requirements
+
+- [yazi (0.4+) or nightly](https://github.com/sxyazi/yazi)
+- [eza (0.20+)](https://github.com/eza-community/eza)
+
+## Installation
+
+### Linux/MacOS
+
+```sh
+ya pack -a ahkohd/eza-preview
+```
+
+## Usage
+
+Add `eza-preview` to previewers in `yazi.toml`:
+
+```toml
+[[plugin.prepend_previewers]]
+name = "*/"
+run = "eza-preview"
+```
+
+Set key binding to switch between list and tree modes in `keymap.toml`:
+
+```toml
+[manager]
+prepend_keymap = [
+  { on = [ "E" ], run = "plugin eza-preview",  desc = "Toggle tree/list dir preview" },
+  { on = [ "-" ], run = "plugin eza-preview --args='--inc-level'", desc = "Increment tree level" },
+  { on = [ "_" ], run = "plugin eza-preview --args='--dec-level'", desc = "Decrement tree level" },
+  { on = [ "$" ], run = "plugin eza-preview --args='--toggle-follow-symlinks'", desc = "Toggle tree follow symlinks" },
+]
+```
+
+List mode is the default, if you want to have tree mode instead when starting yazi - update `init.lua` with:
+
+```lua
+require("eza-preview"):setup({
+  -- Determines the directory depth level to tree preview (default: 3)
+  level = 3,
+
+  -- Whether to follow symlinks when previewing directories (default: false)
+  follow_symlinks = false
+
+  -- Whether to show target file info instead of symlink info (default: false)
+  dereference = false
+})
+
+-- Or use default settings with empty table
+require("eza-preview"):setup({})
+
+```
