+
+# Usage
+
+Create a progress indicator like this:
+   ```swift
+   ProgressIndicatorView(isVisible: $showProgressIndicator, type: .bar(progress: $progress))
+   ```
+   where  
+   `showProgressIndicator` - bool value you may change to display or hide the indicator  
+   `type` - value from `ProgressIndicatorView.IndicatorType` enum  
+
+You may alter it with standard SwiftUI means like this: 
+   ```swift
+   ProgressIndicatorView(isVisible: $showProgressIndicator, type: .bar(progress: $progress))
+        .frame(width: 50.0, height: 50.0)
+        .foregroundColor(.red)
+   ```
+
+### Indicator types
+`default` - progress indicator looks like default iOS UIActivityIndicator.  
+`bar` - line progress bar with a Binding<CGFloat> progress value and background color, default is `Color.clear`:
+  ```swift
+   ProgressIndicatorView(isVisible: $showProgressIndicator, type: .bar(progress: $progress, backgroundColor: .gray)
+       .frame(height: 8.0)
+       .foregroundColor(.red)
+   ```
+  
+`impulseBar` - impulse line bar, works as `bar` indicator with an impulse effect.  
+`dashBar` - discrete line bar, with number of pieces, default is 8:
+   ```swift
+     ProgressIndicatorView(isVisible: $showProgressIndicator, type: .dashBar(progress: $progress, numberOfItems: 8))
+        .frame(height: 8.0)
+        .foregroundColor(.red)
+   ```
+  
+`circle` - cirle progress indicator, with `lineWidth` and `strokeColor`:
+  ```swift
+     ProgressIndicatorView(isVisible: $showProgressIndicator, type: .circle(progress: $progress, lineWidth: 8.0, strokeColor: .red))
+        .frame(height: 8.0)
+        .foregroundColor(.red)
+   ```  
+
+
