Add an HTML, CSS and Javascript Website to my Theme editor

[Eliaa]

 I created a Website for my Onlineshop on my own. Now i want to add the Template to the Shopify Editor so i can do the Backend, but i get always the same Error "Branch isn’t a valid theme". 

Here is my repo if you want to check it out: https://github.com/EAlbanese/RoomVibe

If you're receiving the error message "Branch isn't a valid theme" when trying to add your template to the Shopify editor, it typically indicates that the template you're trying to upload is not in the correct format or structure expected by Shopify
