How to run?

How to run this? I want to edit my level.dat for my bedrock world and change a few things. I never use GitHub so I'm kind of clueless I guess.

It's a site that you can run in your browser, which you can open from here.

Once you open the site, you can either use drag and drop, or the 'Open' button to edit your world's level.dat file. Then you can re-download the edited copy, and move it to where your original level.dat is, which will make your edits apply once you restart the world. Make sure not to be running the game while you make your edits, as they may not apply.
