+
+This module is used to sharpen the pixels of the image using a 3x3 convolution filter.
+#### Usage
+
+```js
+  sequencer.loadImage('PATH')
+           .addSteps('sharpen',options)
+           .run()
+```
+
+where `options` is an object with the property `sharpenStrength`, which can be set to achieve the desired level of sharpening on the image.
+
+
 ## Text Overlay
 
 The modules allows to add text to image in both browser and node environment. We have the options to modify the font-size and also support few font-styles. The text color can also be modified.
