 # XIVLauncher OTP Wrapper
 
-This is a simple wrapper script for Linux that launches `xivlauncher-core` and automatically injects your One-Time Password (OTP) when the launcher requests it.
+This is a wrapper script for Linux that launches `xivlauncher-core` (Native or Flatpak) and automatically injects your One-Time Password (OTP) when the launcher requests it.
 
-## Setup
+## Features
+
+- **Auto-Detection**: Automatically detects if you are using the native `xivlauncher-core` (Arch/AUR) or the Flatpak version.
+- **OTP Injection**: Generates TOTP codes and sends them to the launcher's internal server.
+- **URL Support**: Accepts standard Base32 secrets OR full `otpauth://` URLs (e.g. from QR codes).
+- **Auto-Configuration**: Prompts to fix `launcher.ini` settings if they are incorrect.
+
+## Installation (Steam Deck / Linux Desktop)
+
+The easiest way to install is using the provided installer script.
+
+1.  **Run the Installer:**
+    ```bash
+    ./installer.sh
+    ```
+2.  **Enter Secret:**
+    When prompted, enter your **TOTP Secret** or paste a full **otpauth:// URL**.
+
+**What it does:**
+*   Creates `~/.config/xivlauncher-wrapper/config.json`.
+*   Installs the wrapper to `~/.local/bin/xivlauncher-wrapper`.
+*   Installs a `.desktop` file to `~/.local/share/applications/` so it appears in your application menu.
+
+### Steam Integration (Steam Deck)
+1.  Switch to Desktop Mode.
+2.  Open Steam.
+3.  "Games" -> "Add a Non-Steam Game to My Library".
+4.  Select "XIVLauncher Wrapper" from the list.
+5.  Return to Gaming Mode and launch "XIVLauncher Wrapper".
+
+## Manual Setup
 
 1.  **Configure:**
-    Create the configuration directory and copy the example config.
     ```bash
     mkdir -p ~/.config/xivlauncher-wrapper
     cp config.example.json ~/.config/xivlauncher-wrapper/config.json
     nano ~/.config/xivlauncher-wrapper/config.json
     ```
-    *   `secret`: Enter your TOTP secret key (in Base32 format, usually provided when you set up your authenticator app).
-    *   `launcher_cmd`: The command to launch XIVLauncher (default: `xivlauncher-core`).
+    *   `secret`: Enter your TOTP secret key or `otpauth://` URL.
+    *   `launcher_cmd`: (Optional) The command to launch XIVLauncher. If omitted, the wrapper will auto-detect it.
 
 2.  **Make Executable:**
-    Ensure the script is executable:
     ```bash
     chmod +x wrapper.py
     ```
 
 3.  **XIVLauncher Settings:**
-    Ensure that "Enable XL Authenticator app/OTP macro support" is enabled in XIVLauncher settings.
+    Ensure that "Enable XL Authenticator app/OTP macro support" is enabled in XIVLauncher settings. The wrapper will check for this and prompt you if it's disabled.
 
 ## Usage
 
-Simply run the wrapper instead of the launcher:
+Simply run the wrapper:
 
 ```bash
 ./wrapper.py
 ```
 
-The script will:
-1.  Launch XIVLauncher.
-2.  Wait for the launcher to start its local HTTP server (port 4646).
-3.  Generate the current OTP code.
-4.  Send it to the launcher automatically.
+Or launch "XIVLauncher Wrapper" from your application menu/Steam.
 
-## Steam Deck / Linux Desktop Installation
-
-For Steam Deck or standard Linux desktop users, you can use the provided installer script to set everything up automatically.
-
-1.  **Run the Installer:**
-    ```bash
-    ./install-steamdeck.sh
-    ```
-    Follow the prompts to enter your OTP secret.
-
-2.  **What it does:**
-    *   Creates the configuration file with your secret.
-    *   Installs the wrapper to `~/.local/bin/xivlauncher-wrapper`.
-    *   Installs a `.desktop` file to `~/.local/share/applications/` so it appears in your application menu (and can be added to Steam as a non-Steam game).
-
-3.  **Steam Integration:**
-    *   Switch to Desktop Mode.
-    *   Open Steam.
-    *   "Games" -> "Add a Non-Steam Game to My Library".
-    *   Select "XIVLauncher Wrapper" from the list.
-    *   Return to Gaming Mode and launch "XIVLauncher Wrapper".
