The best way to start on decentralization is to default to a decentralized web browser! If you're already doing that, you should see a purple '.onion available' button in your searchbar. Clicking that will take you to the actual page with tutorialization and resources. If you're on mobile where the button doesn't show, you can just copy and paste "http://6uiio4jrtewftdwuotlj6bb2lftfoatuaa4bupbco25a4sfid3w4yuqd.onion/ipfs/QmTGerwLqQsuvADBwmivK9qwSfhWNwN3r2CQJXkkruh1RQ/selfdecentralization.html" into your browser, and that should also load the page.

If the page doesn't load, there's a 99.9% chance you're not in the correct browser, in which case you should change your default browser to the Tor Browser, as it is by far the most decentralized & secure browser you could possibly use.
