Drupal: content types URL?

I'm new to Drupal and I have a quick question: I've created a content type "news_section" for our site's news, but I have no idea how to access开发者_StackOverflow社区 that. It says that I can access it by going to sitename.com/news_section, but that doesn't seem to work.

Any idea how to do that?

Appreciate your help

Simple and flexible way: install Views module and setup it to show this content type.
Other way: Apply Taxonomy term, make it required, and give to taxonomy term alias path to this way
Harder way: build own module.
