Sorry if this question is a little bit stupid. I think that I must put the theme's files in github but how to make it available for installation on every backdrop site (in https://backdropcms.org/themes/) ?
I'm working for fun and future work on a simple theme based on some parts of Bartik. This is not a professional theme but maybe in the futur.
I can make it accessible from my site but perhaps it is better directly on backdropcms.org?
Are there procedures to follow, a particular license, rules, etc.?
