-## Step 1: Add or enable a source and get its write key
+## Step 1: Get your source write key
 
-You can either create a new source or turn on Auto-Instrumentation for an existing source. Both methods let you retrieve the `writeKey` that you’ll need later.
+You’ll need the `writeKey` from an existing Segment source:
 
-### Create a new source
-
-1. In your Segment workspace, navigate to **Connections > Auto-Instrumentation**.
-2. Select **Add source**, give the source a name, and click **Save**.
-3. Return to **Connections > Sources** and select the new source you just set up.
-4. In the **Initialize the Client** section, copy the `writeKey` shown in the code block.
-
-### Enable Auto-Instrumentation on an existing source
-
-If you want to use an existing source, copy its `writeKey` from **Initialize the Client**. After you install the SDK (Step 2), return to the source settings to turn on Auto-Instrumentation:
-
-- **Web:** **Connections > Sources > [source] > Settings > Analytics.js > Auto-Instrumentation** and toggle it on.
-- **Mobile:** **Connections > Sources > [source] > Settings > Advanced > Auto-Instrumentation** and toggle it on.
+1. In your Segment workspace, go to **Connections > Sources**.
+2. Select your source.
+3. From the source's overview tab, go to **Settings > API Keys**.
+4. Copy the `writeKey` shown in the code block.
 
 ## Step 2: Add dependencies and initialization code
