 ## How to Signal
 
 Now that we’ve covered the basics about how the bonding curve works, this is how you will proceed to signal on a subgraph. Within the Curator tab on the Graph Explorer, curators will be able to signal and unsignal on certain subgraphs based on network stats. For a step-by-step overview of how to do this in the Explorer, [click here.](/network/explorer)
