-Requires forkchoice update to be sent for block building, on public testnets run beacon node modified to send forkchoice update on every slot [example modified beacon client (lighthouse)](https://github.com/flashbots/lighthouse)
+You will need to run a modified beacon node that sends a custom rpc call to trigger block building. You can use the modified [prysm fork](https://github.com/flashbots/prysm) for this.

 ## How it works
 
-* Builder polls relay for the proposer registrations for the next epoch
-
-Builder has two hooks into geth:
-* On forkchoice update, changing the payload attributes feeRecipient to the one registered for next slot's validator
-* On new sealed block, consuming the block as the next slot's proposed payload and submits it to the relay
-
-Local relay is enabled by default and overwrites remote relay data. This is only meant for the testnets!
+* Builder polls relay for the proposer registrations for the next epoch when block building is triggered
+* If both local relay and remote relay are enabled, local relay will overwrite remote relay data. This is only meant for the testnets!
 
 ## Limitations
 
-* Blocks are only built on forkchoice update call from beacon node
 * Does not accept external blocks
 * Does not have payload cache, only the latest block is available
