trouble with PR's

im pretty stupid and autistic so I have a hard time reading this guide, I have the files that I want to change but I don’t have that notepad file that adds the text to the changelog and I have no experience with github or anything similar. in the simplest way, what do I do to set up a basic pull request and if there are any video guides, or you decide to make one, please link it

for changelog just edit the end of the template thats like

:cl:

  • add: Added fun!
