-## Why❓
-
 ## Features:
+- Easy to integrate. All you have to do is add the view into your XML and listen for the value changes.
+- Highly customizable. Change width, height, color, distance between indicators. Change the color and sze of the texts in the ruler in XML or dynamically from your java or kotlin code.
+- Extremely lightweight 🏋.
 
 ## How to use this library?
 - ### Gradle dependency: 
 - Add below dependency into your build.gradle file.
-
 ```groovy
 compile 'com.kevalpatel2106:ruler-picker:1.0'
 ```
+- For other build systems see [Import.md](/.github/IMPORT.md).
 
 ## How to use?
+- Add `RulerValuePicker` inside your XML layout.
+```xml
+<com.kevalpatel2106.rulerpicker.RulerValuePicker
+    android:id="@+id/ruler_picker"
+    android:layout_width="match_parent"
+    android:layout_height="100dp"
+    android:background="@android:color/holo_orange_dark"
+    app:indicator_color="@android:color/white"
+    app:indicator_interval="14dp"
+    app:indicator_width="2dp"
+    app:max_value="120"
+    app:min_value="35"
+    app:notch_color="@android:color/white"
+    app:ruler_text_size="6sp"/>
+
+```
+- Library provides XML attributes to customize the `RulerValuePicker` or you can customize it dynamically using Java/Kotlin code.
+
+|Attribute|Type|Java/Kotlin|Description|
+|:---:|:---:|:---:|:---:|
+|indicator_color|Color|`setIndicatorColor()`|Change the color of the indicator in the ruler.|
+|indicator_interval|Dimensions|`setIndicatorIntervalDistance()`|Change the distance between two indicators in the ruler.|
+|indicator_width|Dimensions|`setIndicatorWidth()`|Change the width (thickness) of the indicator.|
+|notch_color|Color|`setNotchColor()`|Change the color off the notch at the top of the ruler.|
+|ruler_text_size|Dimensions|`setTextSize()`|Change the size of the text that displays the values in the ruler.|
+|ruler_text_color|Color|`setTextColor()`|Change the color of the text that displays the values in the ruler.|
+|long_height_height_ratio|Fraction|`setIndicatorHeight()`|Change the height of the long indicator. The value is between 0 to 1 where 1 indicates the height of the ruler. This value must be greater than or equal to `long_height_height_ratio`.|
+|short_height_height_ratio|Fraction|`setIndicatorHeight()`|Change the height of the short indicator. The value is between 0 to 1 where 1 indicates the height of the ruler. This value must be less than or equal to `short_height_height_ratio`.|
+|max_value|Integer|`setMinMaxValue()`|Maximum possible value to display in the ruler. This value must be greater than `min_value`.|
+|min_value|Integer|`setMinMaxValue()`|Minimum possible value to display in the ruler. This value must be greater than `max_value`.|
+
+- Set the initially selected value.
+```java
+rulerValuePicker.selectValue(55 /* Initial value */);
+```
+
+- Set up a `RulerValuePickerListener` callback listener to get notify when the selected value changes. Application will receive the final selected value in `onValueChange()` callback.
+
+#### Java:
+```java
+rulerValuePicker.setValuePickerListener(new RulerValuePickerListener() {
+    @Override
+    public void onValueChange(final int selectedValue) {
+        //Value changed and the user stopped scrolling the ruler.
+        //Application can consider this value as final selected value.
+    }
+
+    @Override
+    public void onIntermediateValueChange(final int selectedValue) {
+        //Value changed but the user is still scrolling the ruler.
+        //This value is not final value. Application can utilize this value to display the current selected value.
+    }
+});
+```
+#### Kotlin:
+```kotlin
+rulerValuePicker.setValuePickerListener(object : RulerValuePickerListener {
+    override fun onValueChange(value: Int) {
+        //Value changed and the user stopped scrolling the ruler.
+        //You can consider this value as final selected value.
+    }
+
+    override fun onIntermediateValueChange(selectedValue: Int) {
+        //Value changed but the user is still scrolling the ruler.
+        //This value is not final value. You can utilize this value to display the current selected value.
+    }
+})
+```
