Describe the issue

When I try to build a graph for a contract from a specific chain (EVM), I am not able to select such chain

✔ Network · N/A

  The chain list is populated from the Networks Registry:

  https://github.com/graphprotocol/networks-registry

  To add a chain to the registry you can create an issue or submit a PR

Should refer people to the Chain Integration Process instead of submitting a PR to the supported networks registry.
