Pages not found – drupal 8

Just installed drupal 8.2.0 but except for frontage no other pages are to be found.
On drupal.org site I found this:

«Drupal 8.x
In Drupal 8, clean URLS are enabled by default and can’t be disabled. However, a rewrite module must be installed on your web server.»

But the link to the rewrite module doesn’t work, does anyone know where to find the module or how to fix the problem in any other way. I´m new to this, I´ not a programmer – thankful for any help
