 ## Calling OSDU API's
 
-The cliclient.py module contains the _CliOsduClient _class that simplifies interacting with the OSDU backend. _CliOsduClient _currently uses the separate osdu-sdk package which contains backend code seperated out from the original CLI. Future updates might align with a future OSDU standard SDK. Using the _CliOsduClient_ you can make HTTP REST calls direclty agains the API's. Certain API's e.g. Search have wrapper classes that simplify the API usage.
