How to add custom chain, like Goerli?

[zydjohnHotmail]

Hello:
I want to add some feature to the default Goerli test net. And I found this repo, I see that this repo can explore multiple chains, but there is no Goerli chain in the Json list.
If I want to use this repo to explore Goerli chain, how can I modify the Json chain list?
By the way, I wrote a smart contract and deployed onto Goerli chain, I can see the deployment went well. But I want to test the smart contract deployed on Goerli chain with explorer, however, the default Goerli chain explorer didn’t have such feature.
I want to know if I can modify this repo, so I can use it to test smart contract deployed on Goerli chain?
Finally, if there is other custom blockchain which I want to be able to launch blockchain explorer, to use this repo, what kind of information is necessary?
Please advise,
Thanks,

Hi our blockchain is based on utxo style scheme and I think you looking for Ethereum style right?
This won't work with our explorer, not without big refactoring.

Hi,
Thanks for your reply. I have yet another question: there is one blockchain explorer at this url: https://explorer.btcbam.com/
I think this one is based on utxo style scheme, I want to know if I can use the repo to build an explorer for this blockchain explorer. I want to add some features to the explorer, like test some smart contracts?
Let me know what kind of information is necessary to do this?
Thanks,
