<human>:  I'm trying to fix a bicycle chain. Can you explain how to do it?
<bot>: First, you'll need to find where the chain is broke. You should be able to see a visible gap between two of the links. Once you have located the break, you'll need to carefully remove the broken section of chain with a pair of pliers. Next, take a quick-link, a small flat metal connector that looks like an open loop, and fit one side of the link into the inside of the chain. Then fit the other side of the link into the outside of the chain and close it around the links. To make sure the quick-link is closed properly, give it a tug to see if it is secure. Finally, put the chain back on the bicycle and it should be ready to go!
