Pushing folder and its content to Student Repos

[erradi]

Suppose that the initial content I would like to push to the student repos is organized in subfolders such as:
index.html
css/styles.ccs
imgs/img1.png
imgs/img2.png
I have tried to use push_files action to place the above folders hierarchy into the repository for each student but it did not work.
What is the best way to achieve the above?
Thanks for your appreciated help.
