+## Preparation
+To help you test the Activity Feed quickly, add this sample collection to **App OnStart** or any button’s **OnSelect**:
 
+```
+ClearCollect(
+    colActivity,
+    {
+        Name: "New Product Presentation",
+        Date: DateValue("12/25/2025"),
+        Details: "You have an upcoming task"
+    },{
+        Name: "Finish the presentation",
+        Date: DateValue("11/25/2025"),
+        Details: "You have an upcoming task with <b>John Doe</b>"
+    },{
+        Name: "New Product Presentation",
+        Date: DateValue("11/05/2025"),
+        Details: "You have an upcoming appointment with <b>John Doe</b>"
+    },{
+        Name: "Invite Acme to the next month",
+        Date: DateValue("9/25/2025"),
+        Details: "You have an upcoming task"
+    }
+)
+```
+The gallery in the YAML snippet uses:
+```
+Items = Sort(colActivity, Date, SortOrder.Descending)
+```
+Replace **colActivity** with any source you prefer.
