-## LNbits as an LNURL-withdraw fallback
+<img src="https://i.imgur.com/aEBpwJF.png" style="width:800px">
 
-LNURL has a fallback scheme, so if scanned by a regular QR code reader it can default to a URL. LNbits exploits this to generate an instant wallet using the [LNURL-withdraw](https://github.com/btcontract/lnurl-rfc/blob/master/lnurl-withdraw.md).
+## LNbits API
 
-![lnurl fallback](https://i.imgur.com/CPBKHIv.png)
+LNbits has a powerful API, many projects use LNbits to do the heavy lifting for their bitcoin/lightning services.
 
-Using **lnbits.com/?lightning="LNURL-withdraw"** will trigger a withdraw that builds an LNbits wallet.
+<img src="https://i.imgur.com/V742sb9.png" style="width:800px">
-Example use would be an ATM, which utilizes LNURL, if the user scans the QR with a regular QR code scanner app, they will still be able to access the funds.

+## LNbits node manager
 
-## LNbits as an instant wallet
+LNbits comes packaged with a light node management UI, to make running your node that much easier.
 
-Wallets can be easily generated and given out to people at events. "Go to this website", has a lot less friction than "Download this app".
