+
+A Yazi plugin for searching file content or filenames using `ripgrep` with `fzf` preview
+
+> [!NOTE]
+> The latest main branch of Yazi is required at the moment.
+>
+> Support shell: `bash`, `zsh` ,`fish` ,`nushell`
+
+## Dependencies
+
+- fzf
+- ripgrep
+- bat
+- nullshell(only windows need)
+
+## Install
+
+```bash
+git clone https://github.com/DreamMaoMao/fg.yazi.git ~/.config/yazi/plugins/fg.yazi
+```
+
+```powershell
+git clone https://gitee.com/DreamMaoMao/fg.yazi.git $env:APPDATA\yazi\config\plugins\fg.yazi
+```
+
+
+## Usage
+
+This option uses `ripgrep` to output all the lines of all files, and then uses `fzf` to fuzzy matching.
+
+```toml
+[[manager.prepend_keymap]]
+on   = [ "f","g" ]
+run  = "plugin fg"
+desc = "find file by content (fuzzy match)"
+```
+
+The following option passes the input to `ripgrep` for a match search, reusing the `rg` search each time the input is changed. This is useful for searching in large folders due to increased speed, but it does not support fuzzy matching.
+
+```toml
+[[manager.prepend_keymap]]
+on   = [ "f","G" ]
+run  = "plugin fg --args='rg'"
+desc = "find file by content (ripgrep match)"
+```
+
+```toml
+[[manager.prepend_keymap]]
+on   = [ "f","f" ]
+run  = "plugin fg --args='fzf'"
+desc = "find file by filename"
+```
