-## Creating a CDI segment
+### Step 1: Set up your source
+
+Before creating your first CDI Segment, set up a new Connected Source with your data warehouse by following the steps in [Connected Sources]({{site.baseurl}}/user_guide/data_and_analytics/cloud_ingestion/connected_sources/).
+
+### Step 2: Create a segment
+
+First, create a new [Segment Extension]({{site.baseurl}}/user_guide/engagement_tools/segments/segment_extension/), then select **Full refresh**.
+
+![]({% image_buster /assets/img/segment/segment_extension_modal.png %}){: style="max-width:70%;"}
+
+For your data source, choose **CDI Data Tables**.
 
-After your CDI integration is set up, create your CDI segment by doing the following. 
+![]({% image_buster /assets/img/segment/cdi_data_tables.png %}){: style="max-width:80%;"}
 
-1. Create a new [Segment Extension]({{site.baseurl}}/user_guide/engagement_tools/segments/segment_extension/) and select the **Full refresh** option. <br>![]({% image_buster /assets/img/segment/segment_extension_modal.png %}){: style="max-width:50%;"}<br><br>
+As part of your CDI setup, you can select from different connections to use in CDI segments. Each connection has a specific set of data tables. Your development team can configure your connections and data tables during CDI setup.
 
-2. Select **CDI Data Tables** as your data source. <br>![]({% image_buster /assets/img/segment/cdi_data_tables.png %}){: style="max-width:50%;"}<br><br>
+To view the available data tables, select **Reference**. When you're ready, select a connection.

-4. Select a connection. <br>![]({% image_buster /assets/img/segment/connection_schema.png %}){: style="max-width:70%;"}<br><br>
+Next, write the SQL for your segment using [the Braze SQL syntax]({{site.baseurl}}/user_guide/engagement_tools/segments/sql_segments/#writing-sql).
 
-5. Write the SQL for your segment using [our guidelines]({{site.baseurl}}/user_guide/engagement_tools/segments/sql_segments/#writing-sql). All CDI segments must use `external_user_id` as the selected column, and your `external_user_id` should match the one set in Braze for users. If your query results include users that don't exist in Braze, those users will be ignored. Braze will not create new users based on the output of your CDI segment.

 - Your query might timeout when it reaches your maximum runtime, which is set up for each connection sync on the **Cloud Data Ingestion** page. The maximum runtime allowed is 60 minutes.
