You can use the SDK by simply specifying the adapters to be used. E.g. Edge Cloud Platform: i2Edge, 5G core: Open5Gs

Example available in [`/examples/example.py`](examples/example.py)

```python

from sunrise6g_opensdk import Sdk as sdkclient

def main():

    client_specs = {

        "edgecloud": {

            "client_name": "i2edge",

            "base_url": "http://IP:PORT",

        },

        "network": {

            "client_name": "open5gs",

            "base_url": "http://IP:PORT",

            "scs_as_id": "id_example",

        },

    }

    clients = sdkclient.create_clients_from(client_specs)

    edgecloud_client = clients.get("edgecloud")

    network_client = clients.get("network")

    print(edgecloud_client.get_edge_cloud_zones())

    print(network_client.get_qod_session(session_id="example_session_id"))

if __name__ == "__main__":

    main()

python3 -m examples.example

```
