 - **InMemoryConfigurationStorage**: Temporary in-memory storage for testing
 - **Custom implementations**: Implement your own configuration storage
 
-No additional configuration files are required for basic usage. Authentication settings are managed programmatically through the SDK.
+#### **Requirement for client**
+
+If you are accessing keepersdk from a new device, you need to ensure that there is a config.json file present from which the sdk reads credentials. This ensures that the client doesn't contain any hardcoded credentials. Create the .json file in .keeper folder of current user, you might need to create a .keeper folder. A sample showing the structure of the config.json needed is shown below:

+```
