+## Data Source
+Each `MultiProgressView` needs to conform to the `MultiProgressViewDataSource` protocol:
+
+```swift
+func numberOfSections(in progressView: MultiProgressView) -> Int {
+    return 1    // Return the number of section of your MultiProgressView
+}
+
+func progressView(_ progressView: MultiProgressView, viewForSection section: Int) -> ProgressViewSection {
+    guard let progressView = progressView as? CustomProgressView() else { return ProgressViewSection() }
+
+    // Customize your progressView here...
+
+    return progressView
+}
+```
+
+## Delegate
+
+Optionally, a `MultiProgressView` can conform to the `MultiProgressViewDelegate` protocol, which define a method to recognize a tap event on `MultiProgressView`'s sections:
+
+```swift
+func progressView(_ progressView: MultiProgressView, didTapSectionAt index: Int) {
+    for (progressViewIndex, view) in progressViews.enumerated() where view === progressView {
+      print("Tapped progressView \(progressViewIndex) at section \(index)")
+    }
+}
+```
