 * See owned fungible tokens and NFTs
 * Display recent transactions
 * Go directly to the successful/failed transaction in the Sui Explorer
+* Try out our demonstration [NFT dApp](https://github.com/MystenLabs/sui/tree/main/wallet/examples/demo-nft-dapp) available [in the Cloud](http://sui-wallet-demo.s3-website-us-east-1.amazonaws.com/)
 
 Note, the wallet will auto split/merge coins if the address does not have a Coin object with the exact transfer amount. See the [Use](#use) section for guidance on employing these features.
 
 ## Purpose
 
-Initially, the Sui Wallet Browser Extension is aimed at Sui developers for testing purposes. As such, the tokens are of no value (just like the rest of [DevNet](https://github.com/MystenLabs/sui/blob/main/doc/src/explore/devnet.md)) and will disappear each time we reset the network. In time, the Sui Wallet Browser Extension will be production ready for real tokens.

-This browser extension is a pared-down version of the [Sui Wallet command line interface (CLI)](https://github.com/MystenLabs/sui/blob/main/doc/src/build/wallet.md) that provides greater ease of use for the most commonly used features. If you need more advanced features, such as merge/split coins or make arbitrary [Move](https://github.com/MystenLabs/sui/blob/main/doc/src/build/move.md) calls, instead use the [Wallet CLI](https://github.com/MystenLabs/sui/blob/main/doc/src/build/wallet.md).
