How to make a own template?

Description

I wanted to ask: I want to make a own, modified version of the "Sublime" theme. I downloaded the theme (zip-file from Github), renamed the folders and the name inside the read.me file and uploaded it under, lets say "newname-v1.0.zip".

But it shows up incorrectly, the version is displayed wrong, the preview-image is missing (but present in the zip) and all changes I made do not reflect...

How can I create a own theme? I dont want to edit the original Sublime-files, because I assume with the next update, all work is gone. Simply just locally, nothing on Github etc...
