+## How to use
+
+### You can refer to this Video:
+https://youtu.be/Dnm3SI_OIko
+
+### OR Follow these steps:
+> Step 1. Add this maven dependency to your build.gradle (project) file
+
+```gradle
+allprojects {
+		repositories {
+			...
+			maven { url 'https://jitpack.io' }
+		}
+	}
+  ```
+ >Step 2. Add the dependency to your build.gradle (app) file
+ 
+ ```gradle
+ dependencies {
+	        implementation 'com.github.Miihir79:DrawingCanvas:1.0.1'
+	}
+  ```
+
+  >Step 3. Add the XML code 
+  
+  ```XML
+  <com.mihir.drawingcanvas.drawingView
+        android:id="@+id/drawing_view"
+        android:layout_width="match_parent"
+        android:layout_height="match_parent">
+

+>Step 4. Refrence the canvas in XML to use it's functions
+
+```Kotlin
+    drawing_view.setBrushAlpha(120)// values from 0-255
+    drawing_view.setBrushColor(R.color.white) 
+    drawing_view.setSizeForBrush(12) // takes value from 0-35
+    drawing_view.undo() 
+    drawing_view.redo()
+    drawing_view.clearDrawingBoard()
+
+```
+
