The "tutorial" link redirected to not found page

[kevinsalimi]

I've just studied the Readme.md contents then I run into a wrong behavior.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Live Demo' part
2. Click on 'tutorial'
3. It redirects you to a not found page.

Expected behavior
What I expected is, it should redirect me to the Home page of the document.

Screenshots

I would like to fix it as my first contribution on the project. :)
