Here click on the red "Top-Up Balance" button.
Then the next page will look like this (picture under this section). here you can click the button that says "from" and choose how you are going to deposit money. For this example, I'm going to use the Bitcoin Lightning network. hence I chose it. and if you click the "To" button next to the "From" button you can choose how you want to receive it. you can choose whether you want it to get deposited as Bitcoin or as USD. So for this example, I have chosen my USD balance.

And the next thing we have to do is create a Lightning invoice. you can simply put the BTC amount you want to receive and click generate button and the website will generate an invoice for you. So I put 0.00035 as the BTC amount and click the generate button. and the website generated an invoice for me. (check the next picture)

So now all I have to do is use my Bitcoin Lightning wallet to Scan the QR code showing on the webpage and confirm the transaction. And after I confirm it in the app the money instantly got deposited to my USD balance in my Bitrefill account. You can see that in the pictures below.
