Good Day, I would like to learn how to import custom Boostrap themes i own into my Odoo website, packaging them as theme_modules. 
In particular, I need to enlarge my building block library with more snippets. 

So I created a new empty theme_module following the documentation ( www.odoo.com/documentation/8.0/howtos/themes.html ) then I started copy paste code blocks from a free test Bootrap theme i have (you can find and download it here bootstrapzero.com/bootstrap-template/worthy ) but i'm stuck.
Could you please help me showing me how to properly import them or at least leading me to a good tutorial/documentation (free)

I also followed a bit this guide but it didn't help very much:

Thanks for your help
