+## Usage
+
+`EngineeringMode` can be added to any SwiftUI view easily. Typically, it's used with a [Sheet](https://developer.apple.com/design/human-interface-guidelines/sheets).
+
+
+### **Basic usage with a sheet**
+```swift
+import EngineeringMode
+
+//...
+
+.sheet(isPresented: $showingEngineeringModeSheet) {
+  EngineeringMode()
+}
+```
+
+### **Custom Views**
+
+To add a custom view to the existing Engineering Mode screen, just pass in `customViews` and `customViewTitles`. Optionally, if you want Custom Views to show before the other views, then add `showCustomViewsFirst`.
+
+```swift
+EngineeringMode(
+  customViews: [AnyView],
+  customViewTitles: [String],
+  showCustomViewsFirst: Bool
+)
+```
+
+⚠️ Important: 
+- `customViews` takes in an `AnyView` - please cast it to that.
+- `customViews` and `customViewTitles` should have the same number of array elements! Each custom view should have a title, otherwise the app will crash.
+
+**Example**
+
+```swift
+EngineeringMode(
+  customViews: [AnyView(MyCustomView())],
+  customViewTitles: ["Test"],
+  showCustomViewsFirst: true
+)
+```
