the text i added is -
For Windows Users: Important Note on WSL (Windows Subsystem for Linux)
If you are using a Windows system, you must have Windows Subsystem for Linux (WSL) installed and configured with an Ubuntu distribution. The installation commands for the Gaia node are Linux-based and require a Linux environment to run, which WSL provides on Windows.
