+### 3. Install WhisperX
 
-`pip install git+https://github.com/m-bain/whisperx.git`
+You have several installation options:
 
-If already installed, update package to most recent commit
+#### Option A: Stable Release (recommended)
+Install the latest stable version from PyPI:
 
-`pip install git+https://github.com/m-bain/whisperx.git --upgrade`
+```bash
-
+pip install whisperx
-If wishing to modify this package, clone and install in editable mode:
 ```
-$ git clone https://github.com/m-bain/whisperX.git
+
-$ cd whisperX
+#### Option B: Development Version
-$ pip install -e .
+Install the latest development version directly from GitHub (may be unstable):
+
+```bash
+pip install git+https://github.com/m-bain/whisperx.git
 ```
 
+If already installed, update to the most recent commit:
+
+```bash
+pip install git+https://github.com/m-bain/whisperx.git --upgrade
+```
+
+#### Option C: Development Mode
+If you wish to modify the package, clone and install in editable mode:
+```bash
+git clone https://github.com/m-bain/whisperX.git
+cd whisperX
+pip install -e .
+```
+
+> **Note**: The development version may contain experimental features and bugs. Use the stable PyPI release for production environments.
