I'm a Drupal newbie who just got a first site installed. I want to add the Drutex module. I downloaded it and extracted it to the correct place. The docs say that the next steps are:

2) Go to the module admin section and enable "drutex".

3) Go to the input-filters admin section and create a new input format. You can choose an arbitrary name, but "DruTeX" would make sense. When you create a new format, you can select an input filter from a list: Just choose DruTeX.

What do those steps mean? What/where is the "module admin section"?? (Section of what??) How do I "enable" a module there?

And where is the "input-filters admin section", and how do I ceate a new input format there?

Perhaps somebody who's done this before can make sense of this; I cannot. Your help earnestly solicited.
