 ## Introduction
 
-Implementation of a **https://darwinia.network** node in **Rust** based on the **Substrate** framework.
+Implementation of a **https://darwinia.network** node based on the **[Polkadot-sdk](https://github.com/paritytech/polkadot-sdk)** framework.
 
 This repo contains the following networks:
 
-1. the **Darwinia main network**, the parachain on the Polkadot, and its test network **Pangoro**.
-2. the **Crab main network**, the parachain on the Kusama, and its test network **Pangolin**.
+* the **[Darwinia main network](https://docs.darwinia.network/evm/chains/darwinia/)**, the parachain on the Polkadot.
+* the **[Crab main network](https://docs.darwinia.network/evm/chains/crab/)**, the parachain on the Kusama.
+* the **[Pangolin test network](https://docs.darwinia.network/evm/chains/pangolin/)**, the official testnet for production networks, the parachain on the Rococo.
