+# Fish Installer Script
+
+Automates installation and setup of the [Fish shell](https://fishshell.com/), the [Fisher](https://github.com/jorgebucaran/fisher) plugin manager, and a curated set of plugins.  
+The script detects your OS/package manager, installs Fish (if needed), ensures Fisher is present, installs/updates plugins, and can optionally set Fish as your default shell.
+
+---
+
+## Features
+
+- **OS detection** for common package managers (`apt`, `dnf`, `pacman`, `zypper`, `brew`).
+- **Installs Fish** if missing; skips if already installed.
+- **Installs Fisher** if missing; skips if already installed.
+- **Installs/updates plugins** (listed below).
+- **Optional update checks** for Fish and plugins.
+- **Optional default shell change** via final prompt.
+
+---
+
+## Supported Platforms (via package manager)
+
+- Debian/Ubuntu and derivatives — `apt`  
+- Fedora — `dnf`  
+- Arch/Manjaro — `pacman`  
+- openSUSE — `zypper`  
+- macOS — `brew` (requires Homebrew pre-installed)
+
+> If your distro isn’t listed, you can still run Fish/Fisher manually, then re-run the installer for plugin setup.
+
+---
+

+
+- Internet connectivity

+- `sudo` privileges for package installation
+
+---

+## Typical Output (abridged)
+
+    ✓ Detected debian (apt)
+    ✓ Fish already installed
+    • Checking Fish updates…
+    ✓ Skipped update check
+    ✓ Fisher already present
+    ✓ All requested plugins already installed
+    ? Set Fish as your default shell now? (y/N)

+    
+-   **Permission denied:** Re-run with a user that has `sudo` privileges.
+    
+-   **Terminal still using old shell:** Log out/in or run `chsh -s /usr/bin/fish` (path may vary; the script offers to do this).
