Ah, gothca! Yeah, the dev's answered a similar question earlier;

"In terms of browser based anonymous blockchain, we're able to show the world that everything from transactions to mining can be done without the need to download anything."
 
So you can mine/add a web miner via services like https://crypto-loot.com (who support uPlexa), but you can also mine using your mobile phone, or traditional CPU's GPU's; https://www.uplexa.com/ (miners section near the top).

We also have a community-made  hardware benchmark page, to help you determine how much you can earn/mine; https://www.uplexamining.com/hw-benchmarks/

Hope this helps! It might be that the dev's change the title of this thread at some point (if that's even possible on here)
