+## Installation and Usage (Compiled Executable)
+
+For users who prefer a standalone application without needing to install Python or manage dependencies, a compiled executable is available for Linux.
+
+1.  **Download the Executable:**
+    *   Go to the [Gitea Releases page](https://gitea.ramforth.net/ramforth/youtube-chat-webhook-v2/releases).
+    *   Download the `pytchat_listener` executable from the latest release (e.g., `v0.1.0-alpha`).
+
+2.  **Make Executable:**
+    *   Open your terminal and navigate to the directory where you downloaded the executable.
+    *   Make the file executable:
+        ```bash
+        chmod +x pytchat_listener
+        ```
+
+3.  **Run the Executable:**
+    *   Execute the program directly:
+        ```bash
+        ./pytchat_listener
+        ```
+
+4.  **Enter Video ID:**
+    *   The program will prompt you to "Enter the YouTube Live Stream Video ID:". Paste the 11-character ID of the live stream you wish to monitor and press Enter.
+
+5.  **Observe Chat:**
+    *   The program will then start fetching and displaying live chat messages in your terminal.
+
+6.  **Save Chat Log:**
+    *   To exit the program gracefully, press `Ctrl+C`. You will then be prompted if you want to save the chat log.
+
+**Note:** This executable is compiled for Linux. If you are on a different operating system (e.g., Windows, macOS), you will need to follow the "Installation Steps" above to run the script from source.

 ## User Colors Persistence (`user_colors.json`)
 
 The script assigns unique, persistent colors to chatters. This mapping is stored in a file named `user_colors.json` in the project directory.
