# Generate Your First Substreams

These tutorials demonstrate how to quickly index on-chain data for your application across various blockchains using the Substreams CLI.

**Tip**: Using Claude Code, Cursor, or VS Code with AI? Install the [Substreams agent skills](/how-to-guides/develop-your-own-substreams/general/agent-skills.md) to give your AI assistant expert knowledge of Substreams patterns as you work through these tutorials.

Substreams data streams are available on the chains listed [here](/reference-material/chain-support/chains-and-endpoints.md). To support Substreams a [Firehose](https://thegraph.com/docs/en/new-chain-integration/) endpoint must be available.

If your blockchain is not supported, please ask in Discord. Then, consult the relevant ecosystem guide to get started using Substreams real-time data streams:
