 ## 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](../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)](../build/cli-client.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](../build/move.md) calls, instead use the [Sui CLI client](../build/cli-client.md).
