+> Version 2.0.0 introduces breaking changes with the adoption of Request objects for all API methods.

 ### Create client instance
 
-Once created, you will create an instance of the NavitiaClient class with the following:
+Create an instance of the NavitiaClient class with your authentication token:
 
 ```python

+
+A base URL for Navitia IO is hardcoded and provided to NavitiaClient by default. It can be updated using the `base_navitia_url` parameter.
+
+###  Access APIs data
+
+URLs are mapped as properties in the `NavitiaClient` class. You can find the mapping [here](docs/api_support/).
+
+#### Simple APIs (Coverage, Datasets, Contributors)
+
+For simple APIs like coverage, datasets, and contributors, you can call methods directly:
+
+```python
+# Get coverage information
+regions = client.coverage.list_coverage_regions()
+
+# Get datasets for a region
+datasets, pagination = client.datasets.list_datasets(region_id="fr-idf")
 ```

+#### APIs with Request Objects (Journeys, Places, Schedules, etc.)

 ### Pagination
 
-A couple of APIs are paginated, in particular the public transporations APIs.. In such case, you can navigate in the response using the parameters `start_page` and `count`.
+Several APIs are paginated, particularly the public transportation APIs. You can navigate through results using the `start_page` and `count` parameters in Request objects:

+
+# Request with pagination
+request = JourneyRequest(
+    from_="stop_area:RAT:SA:GDLYO",

+    start_page=0,  # First page
+    count=10       # 10 results per page
+)
+
+journeys = client.journeys.list_journeys(request=request)
+```
 
-An object `Pagination` will be provided by the impacted methods to help you navigating.
