I mention it in the course; but the course is for beginners but you should have a bit of knowledge to do this. You can do it as a completely new beginners but make sure the resources that I have linked are fully understood.

The badge doesn't actually hold any value. It's just symbolic. Hopefully one day it can mean something.

If you are stuck and you are confused about something just message me! You can also use the contact option here to contact me!

Of course! Share your mod with others so they can study it and see changes. Upload it in a zip file because the package file format is not accepted. Also be sure you do not upload anything, offensive, rude or malicious because it will be deleted and you will be banned.
