1. **Chaning the port number for papertlab GUI**

By default, the papertlab GUI runs on port 5000. However, you can easily change this to a different port if needed. This can be useful if port 5000 is already in use on your system or if you need to run multiple instances of papertlab.

### Using the --port Command-line Option

To change the port number, use the `--port` option when starting papertlab. Here's the syntax:

```
papertlab --port=8000
```

2. **Checking the papertlab Version You can easily check which version of papertlab you're currently using. This is useful when reporting issues, following tutorials, or verifying your installation.**

Using the --version Command-line Option To display the version information, use the `--version` option when running papertlab. Here's the syntax: 

```
papertlab --version
```

This command will output the current version of papertlab and exit immediately. For example: papertlab version 1.0.8
