 1. [Download](https://github.com/denizsafak/abogen/archive/refs/heads/main.zip) the repository
 2. Extract the ZIP file
 3. Run `WINDOWS_INSTALL.bat` by double-clicking it
 
 This method handles everything automatically - installing all dependencies including CUDA in a self-contained environment without requiring a separate Python installation. (You still need to install [espeak-ng](https://github.com/espeak-ng/espeak-ng/releases/latest).)
 
+> [!NOTE]
+> You don't need to install Python separately. The script will install Python automatically.
+
+#### OPTION 2: Install using pip
+```bash
+# Create a virtual environment (optional)
+mkdir abogen && cd abogen
+python -m venv venv
+venv\Scripts\activate
+
+# For NVIDIA GPUs:
+pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128
+
+# For AMD GPUs:
+# Not supported yet, because ROCm is not available on Windows. Use Linux if you have AMD GPU.
+
+# Install abogen
+pip install abogen
+```

 ## `Voice Mixer`
 <img title="Abogen Voice Mixer" src='https://raw.githubusercontent.com/denizsafak/abogen/refs/heads/main/demo/voice_mixer.png'>
 
 With voice mixer, you can create custom voices by mixing different voice models. You can adjust the weight of each voice and save your custom voice as a profile for future use. The voice mixer allows you to create unique and personalized voices. (Huge thanks to [@jborza](https://github.com/jborza) for making this possible through his contributions in [#5](https://github.com/denizsafak/abogen/pull/5))
 
+## `Queue Mode`
+<img title="Abogen queue mode" src='https://raw.githubusercontent.com/denizsafak/abogen/refs/heads/main/demo/queue.png'>
+
+Abogen supports **queue mode**, allowing you to add multiple files to a processing queue. This is useful if you want to convert several files in one batch.
+
+- You can add text files (`.txt`) directly using the **Add files** button in the Queue Manager. To add PDF or EPUB files, use the input box in the main window and click the **Add to Queue** button.
+- Each file in the queue keeps the configuration settings that were active when it was added. Changing the main window configuration afterward does **not** affect files already in the queue.
+- You can view each file's configuration by hovering over them.
+
+Abogen will process each item in the queue automatically, saving outputs as configured.
+> Special thanks to [@jborza](https://github.com/jborza) for adding queue mode in PR [#35](https://github.com/denizsafak/abogen/pull/35)
+
+## `About Chapter Markers`
+When you process ePUB or PDF files, Abogen converts them into text files stored in your temporary directory. When you click "Edit," you're actually modifying these converted text files. In these text files, you'll notice tags that look like this:
+
+```
+<<CHAPTER_MARKER:Chapter Title>>
+```
+These are chapter markers. They are automatically added when you process ePUB or PDF files, based on the chapters you select. They serve an important purpose:
+-  Allow you to split the text into separate audio files for each chapter
+-  Save time by letting you reprocess only specific chapters if errors occur, rather than the entire file
+
+You can manually add these markers to plain text files for the same benefits. Simply include them in your text like this:
+
+```
+<<CHAPTER_MARKER:Introduction>>
+This is the beginning of my text...  
+
+<<CHAPTER_MARKER:Main Content>> 
+Here's another part...  
+```
+When you process the text file, Abogen will detect these markers automatically and ask if you want to save each chapter separately and create a merged version.
+
+![Abogen Chapter Marker](https://raw.githubusercontent.com/denizsafak/abogen/refs/heads/main/demo/chapter_marker.png)
+
+## `About Metadata Tags`
+Similar to chapter markers, it is possible to add metadata tags for `M4B` files. This is useful for audiobook players that support metadata, allowing you to add information like title, author, year, etc. Abogen automatically adds these tags when you process ePUB or PDF files, but you can also add them manually to your text files. Add metadata tags **at the beginning of your text file** like this:
+```
+<<METADATA_TITLE:Title>>
+<<METADATA_ARTIST:Author>>
+<<METADATA_ALBUM:Album Title>>
+<<METADATA_YEAR:Year>>
+<<METADATA_ALBUM_ARTIST:Album Artist>>
+<<METADATA_COMPOSER:Narrator>>
+<<METADATA_GENRE:Audiobook>>
