Is there a difference between Magento 2 CE from official site and Magento 2 CE from github
Because I could not find many folders and files, and the file and folder structure is different. What is better for beginners? I want to customize the blank theme, but when I follow the tutorial many folders and files are missing form Magento 2.0 from the official site
What you are referring to are different versions for different needs:
GitHub links
This is the version to use when you want to contribute to the Magento 2 codebase as a developer.
This is the version to use when you want to set up a new shop based on Magento 2
Download versions
The download version is actually the same as the magento2-community-edition from GitHub. Use this if you don't want or can run the composer setup.
This link from the Magento 2 docs describes which version is the best for which need: http://devdocs.magento.com/guides/v2.0/install-gde/continue.html
.zip and extract it in your web server's docroot. For all intents and purposes, this is the same as composer create-project.
