+#### Custom view:
+Present any view you like using the `customView` initializer. It is shown centered like `.alert` and respects `duration` / `tapToDismiss`.
+
+```swift
+.toast(isPresenting: $showToast) {
+    AlertToast {
+        HStack {
+            ProgressView()
+            Text("Uploading…")
+                .font(.headline)
+        }
+    }
+}
+```
+
 You can add many `.toast` modifiers on a single view.
