 ## Overview
 
-Running an RPC node for a parachain enables applications, wallets, and users to interact with the parachain's functionality. This guide applies to **any parachain** in the Polkadot ecosystem, including:
-
-- **System parachains**: Bridge Hub, People Chain, Coretime Chain
-- **Common good parachains**: Collectives, Encointer
-- **Commercial parachains**: Any parachain with a publicly available chain specification
+Running an RPC node for a parachain enables applications, wallets, and users to interact with the parachain's functionality.
 
 Each parachain RPC node provides access through the Polkadot SDK Node RPC (Port 9944), offering native Polkadot API access via WebSocket and HTTP. This setup enables block explorer indexing and provides full compatibility with Polkadot SDK development tools.

 ### Other Parachains
 
-For non-system parachains:
-
-- **Check the parachain's documentation** for official chain specification files
-- **Contact the parachain team** if no public chain spec is available
-- **Export from a running node** using `system_chainSpec` RPC method if you have access to an existing node
+For non-system parachains, check the parachain's documentation for official chain specification files.
 
 **Note**: Throughout this guide, we use **People Chain** as the example. To set up a different parachain, substitute the chain spec file, snapshot path, and chain name with values for your target parachain.
