Quick Intro to Trakt
Trakt.tv is a free service that lets you organize your favorite TV shows and movies, it helps you keeping track of what you’re watching on Kodi. Trakt integrates with a lot of popular media centers and you can also use it from a browser or smart phone app. We are going to focus on two specific Trakt features: Collection and Lists.
The Collection: it’s similar to the library on Kodi, here you’ll add your favorite shows and movies.
1. To view your collection select Collection from the Profile Menu on the top-right corner.
2. Use the Filter to select Shows or Movies.
3. You can Sort the results by Title or Date. 
Lists: You can create your own custom lists here, Trakt comes with a default Watchlist you can use to add all the shows and movies you’d like to check out.
1. To view your lists select Lists from the Profile Menu on the top-right corner.
2. Add new lists using the Add Lists button.
To add a show to your collection using Trakt.tv select “TV” from the Top Menu and click on the green book button located under the image of your preferred show.
1. Use the buttons under each Show to Mark as watched, Add to Collection or Add to a List.
2. You can search for specific shows or movies using the Search Box on the top-left corner.
3. Click on Trending or Popular to explore new shows. 
Be aware that the Watchlist is a temporary list, this means that the movies and shows on this list will be automatically removed once they are marked as watched. On the other hand, the Collection and custom lists are persistent.
