Is it possible to install a local XEL node? Or no because we only have a Lite launch? If it's possible, where would one go about installing one/setting it up? Want to share my laptop computing power while I'm at home on my PC

first go to :
https://github.com/unvo1d/Elastic-XEL-Litewallet , then press the green button on the upper right side then follow the instructions ( compile, run,....)
