-This project extends Metamask capabilities to include support for Polkadot,
-Kusama, and other Substrate- and FRAME-based blockchains in the Polkadot
-ecosystem.
+This project uses the [MetaMask Snaps](https://metamask.io/snaps/) framework to extend MetaMask
+capabilities to include support for Polkadot, Kusama, and other
+[Substrate](https://docs.substrate.io/)- and FRAME-based blockchains in the
+[Polkadot](https://www.polkadot.network/) ecosystem.
 
-## What are Snaps?
+#### Extension
+- `yarn install`
+- `yarn run demo`
 
-> Snaps is a system that allows anyone to safely extend the capabilities of
-> MetaMask. A snap is a program that [Metamask runs] in an isolated environment
-> that can customize the wallet experience.
->
-> For example, a snap can add new APIs to MetaMask, add support for different
-> blockchain protocols, or modify existing functionality using internal APIs.
-> Snaps is a new way to create web3 end user experiences, by modifying MetaMask
-> in ways that were impossible before.
