-## Intel XPU usage
+## Intel XPU environmental variables
 
 For XPUs, we need to set some environmental variables. I have added a `env.sh` script which will activate the conda environment `tts` and set the environmental variables.
 
 ```bash
 $ . env.sh
 ```
+## Usage

+
+```bash
+$ python main.py input.txt
+```
