# Genaral Info Welcome to the Mercury docs! If you made it so far congrats, you're one step away from building amazing indexers on Stellar :) * For custom indexers defined in no time inside your smart contracts head to [Retroshades](https://docs.mercurydata.app/retroshades/introduction-to-retroshades) * For simple contract event and transaction queries go to [Classic](https://docs.mercurydata.app/mercury-classic/introduction) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
