+## 🔑 How to Connect
+
+Create a Keplr wallet to use a supported network below:
+
+| Chain    | Networks             |
+|----------|----------------------|
+| `kujira` | `mainnet`, `testnet` |
+
+From inside the Hummingbot client, run `gateway connect kujira` in order to connect your wallet:
+
+In the private key field you have to put your mnemonic.
+
+```  
+Which chain do you want kujira to connect to? (kujira) >>> kujira
+
+Which network do you want kujira to connect to? (mainnet, testnet) >>> mainnet
+
+Do you want to continue to use node url 'None' for kujira-mainnet? (Yes/No) >>> Yes
+
+Enter your kujira-mainnet wallet private key >>>  *****************************
+***********************************
+
+Enter your kujira account number (input 0 if unsure) >>> 0
+```
+
+If connection is successful:
+
+```  
+The kujira connector now uses wallet [pubKey] on kujira-mainnet  
+```
