 ### Installing
 
-1. Install [Python](https://www.python.org) 3.12.6 (or above), 64-bit version. 
+#### Pre-built Binary
+
+Currently only win_amd64 is supported. No Python installation is needed. You can find the pre-built package at release page.

+#### Install form Source
+
+1. Install [Python](https://www.python.org) 3.12.6 (or above, but < 3.13), 64-bit version. 
 2. Run `install.bat` (for Windows) or `install.sh` (for GNU/Linux or macOS). This automatically installs dependencies listed in `requirements.txt` into a Python virtual environment.
 3. (For Extra Job `ocr` only, not required for basic timeline generation) Install Tesseract OCR v5.3.3.20231005 (or above).

The red box should cover the area where the subtitles are displayed. If not, adjust `dialogRect` under the `bcs`, `default` section and rerun.

 If the video has a resolution too high for the display window, consider adjusting `debugPyrDown` under the `framewise` section.
 
-**Productive Running**: Debug mode significantly slows down the program. After verifying alignments in debug mode, process the full video with debug off. Reset the parameters as instructed in the **Configuration** section and run `MagiaTimeline.bat` (for Windows) or `MagiaTimeline.sh` (for GNU/Linux or macOS). Once the program finishes, you should see a `MagiaTimelineOutput.ass` file generated. As a video maker, you should already be familiar with this file format. Enjoy!
