 `chainData` is a store returning the current JavaScript [CAIP-2 representation](https://github.com/ChainAgnostic/CAIPs/blob/master/CAIPs/caip-2.md) object.
 
+### Example
 
-### Example of information available (vary depending on the chain)
+The information returned by the `chainData` store depends (like all
+other web3 stores) on which chain the current provider is
+connected. If the store has not yet been connected (with `setProvider`
+or `setBrowserProvider`), the store value will be `undefined`.

+You might want to access all chains CAIP-2 data directly without using the

+the list of all CAIP-2 data available.
