+KVService works as a general key-value store. It can be used in many different scenarios. This page lists some of the use cases.
+
+## KVService as a persistence storage
+
+You can use KVService to store the data that needs cross-session persistence.
+
+For example, you can store the user's avatar, nick name, bio, show/hide status of NFT list, or order of these contents, under your web3 app's scenarios.
+
+Using KVservices gives you some benefits:
+
+- The change made by user is verifiable by other user / applications, aka platform-independent. No one (except the user himself) can change the data without a valid signature.
+- The data is stored in a decentralized way, no matter where this data is actually stored. User always has a choice to move their data to other (or self-hosted) platforms.
+  > The actual "migration" function is still under development.
