A unofficial plugin to keep your watched movie history from Jellyfin automatically updated to your Letterboxd diary.
This plugin sends daily updates to the Letterboxd diary informing the films watched on Jellyfin. Since the Letterboxd API is not publicly available, this project uses the HtmlAgilityPack package to interact directly with the website's interface.
