How can I add a theme in VSCode?

I have a theme and I would like to upload it to VSCode editor

But I don't know how to do it. I searched on YouTube and couldn't find it, I searched on Google.

And the results were strange, so how is this done?

Here is a picture of the theme folder:

Solution

Copy the folder with the Theme (containing package.json) to the USER VSC extension folder

C:\Users\username\.vscode\extensions

Or package it in a VSIX file and use the VSC GUI to install. Use the Extension Bar top menu (...) entry Install from VSIX...
