 Boost your Subgraph's efficiency and scalability by using [Substreams](/substreams/introduction/) to stream pre-indexed blockchain data.
 
+## Prerequisites
+
+- Substreams-Powered Subgraphs are no longer available through [Subgraph Studio](http://thegraph.com/studio)
+- Substreams-Powered Subgraphs can be run locally
+- Substreams-Powered Subgraphs can be powered by Indexers on The Graph but will require direct coordination with Indexers in the [#substreams channel in Discord](https://discord.gg/graphprotocol).
+
 ## Overview
 
 Use a Substreams package (`.spkg`) as a data source to give your Subgraph access to a stream of pre-indexed blockchain data. This enables more efficient and scalable data handling, especially with large or complex blockchain networks.
