+## Usage
+
+### Basic Example (Kotlin)
+Firstly, you need to add this custom text view to the layout of the class <br>
+
+``` xml
+    <com.boyzdroizy.simpleandroidbarchart.SimpleBarChart
+        android:id="@+id/simpleBarChart"
+        android:layout_width="match_parent"
+        android:layout_height="match_parent" />
+```
+In your class, using the 'id' from layout, call 'setChartData' method to give values for populate the chart.<br>
+
+```kotlin
+    val chartData = (12 downTo 1).map { Random.nextInt(10, 100) }.toMutableList()
+    val intervalData = (12 downTo 1).map { it }.toMutableList()
+
+    simpleBarChart.setChartData(chartData, intervalData)
+    simpleBarChart.setMaxValue(max)
+    simpleBarChart.setMinValue(0)
+```
