You learned about the hidden part of the internet, the Tor hidden services. Then you downloaded and configured your Tor browser for the first deep dive into this unknown territory. As I mentioned before, the hidden services is a region of the internet that is not crawled and indexed by ordinary search engines like Google and Bing. You have to know the .onion URL of the site that you are looking for. These URLs are not the usual easy-to-remember domain names you see in the clear web. The hidden services URLs are generated text with the .onion ending. Luckily there are popular link collections and wiki sites as your entry points to the hidden services.
