-#### Future Work:
+## Future Work
 Since there is no alternate api for setColorFilter in HMOS platform, custom attribute - "app:likeColor" is currently not supported. As a result, user needs to call the setter function instaLikeView.setLikeColor(colorMatrix) and pass a colorMatrix as an argument which will internally call setColorMatrix(colorMatrix) to change the color of the drawable. Once HMOS platform supports setColorFilter, then this custom attribute can be included.
