Introduction to Silex - A Symfony Micro-framework

Nope. Not at all. A tutorial, is to have the reader enabled to run it and try it, with not much additional external reference.

SF2 comes with a .htaccess file so it is not right to say find nothing on the details.

In particular, this tutorial says it does not like to use web folder as the entry folder, and changed to public. So it is worth mentioning.
