-This project uses the [Spotify Web API](https://developer.spotify.com/web-api/) for managing playlists. Just log in and it will traverse your playlists, finding songs that appear multiple times with the same identifier (Spotify URI) in a given playlist.
 
-If it finds duplicates, they can be removed just pushing a button. And since it doesn't create a whole new playlist, it keeps all the information like creation date and subscribers.
+## Introduction
+Have you ever wanted to remove duplicated songs from your Spotify library? Now you can find and remove them using Spotify Dedup. Spotify Deduplicator is a simple and effective tool for cleaning up your Spotify library. Just log in and it will traverse your playlists, finding duplicate songs. It uses the [Spotify Web API](https://developer.spotify.com/web-api/) to identify songs that appear multiple times in a given playlist. With the press of a button, you can remove duplicate tracks from your playlists and liked songs. It saves time and effort by avoiding the need to manually check for duplicate entries, which can be especially useful for users with large music libraries. No playlists are re-created, ensuring all metadata like creation dates and followers are preserved.

 ### Spotify Web API and Promises
 
 This app is a good example of how to traverse a user's library without incurring in rate limit. Have a look at the code and see how Promises and a Promise Queue are used to control the amount of requests sent to the Spotify Web API. If you are interested in throttling promises, check out [promise-throttle](https://github.com/JMPerez/promise-throttle).
