+# Fish Repotool Plugin
+
+A Fish shell plugin for the repotool repository management system.
+
+## Installation
+
+### Using Fisher
+
+```fish
+fisher install path/to/fish-repotool
+```
+
+### Manual Installation
+
+1. Copy the `conf.d/repotool.fish` file to your fish config directory:
+   ```fish
+   cp conf.d/repotool.fish ~/.config/fish/conf.d/
+   ```
+
+2. Copy the `functions/repotool.fish` file to your fish functions directory:
+   ```fish
+   cp functions/repotool.fish ~/.config/fish/functions/
+   ```
+
+## Configuration
+
+Set the `REPOTOOL_PATH` environment variable to specify where your repositories are stored:
+
+```fish
+set -gx REPOTOOL_PATH "$HOME/my-repos"
+```
+
+If not set, it defaults to `$HOME/repo`.
+
+## Usage
+
+The plugin provides a `repo` alias that sources the repotool function with the following commands:
+
+- `repo get <url>` - Clone a repository if not found
+- `repo worktree list` - List existing worktrees
+- `repo worktree get <name>` - Create or go to a worktree
+- `repo worktree root` - Return to the root directory
+- `repo worktree remove <name>` - Remove a worktree
+- `repo open` - Open the current repository in web browser
+
+## Hooks
+
+The plugin supports hooks that can be placed in `$REPOTOOL_PATH/.hooks/`:
+
+- `before_<hook_name>_cd.fish` - Executed before changing directory
+- `after_<hook_name>_cd.fish` - Executed after changing directory
+
+Hooks can also have `.sh` extension or no extension at all.
+
+## Requirements
+
+- Fish shell 4.0 or later
+- `jq` for JSON parsing
+- The repotool binary installed at `$REPOTOOL_PATH/.bin/repotool`
