Simply point your browser to
Apple's Beta Software Program website and sign in with your Apple account.
After that, you'll register your device for iOS 10 and then get an email when the update is ready - this might not be immediately, mind you, especially since the beta is just starting to roll out to registrants.
Access the Beta Software Program website with your iOS device and you'll be able to download a profile - from there, you can install the iOS 10 beta on your compatible iPhone, iPad, or iPad touch, as further explained here .
In addition to the warning about this being pre-release software, you should certainly make sure your OS and essential files are backed up before beginning installation. That's true with any OS update, but especially when it's something new and unfinished.
