-If some objects are not compatible with DuctTape, there are two ways to use DuctTape.
+#### How to access methods
+
+If you want to access methods of object which is building, `func reinforce(_ handler: (Base) -> Void) Builder<Base>` enable to access methods.
+
+```swift
+let collectionView = UICollectionView().ductTape
+    .backgroundColor(.red)
+    .reinforce { collectionView in
+        collectionView.register(UITableViewCell.self, forCellWithReuseIdentifier: "Cell")
+    }
+    .build()
+```
+
+`Builder` has `func reinforce<T1, ...>(_ t1: T1, ..., handler: (Base) -> Void) Builder<Base>` methods.
+In additional usage, be able to access outside object with `func reinforce` if passing objects as arguments.
+
+```swift
+lazy var collectionView = UICollectionView().ductTape
+    .translatesAutoresizingMaskIntoConstraints(false)
+    .reinforce(view) { collectionView, view in
+        view.addSubview(collectionView)
