Wtf does this do

Jellyfin is a free, open-source media server, think of it as a personal Netflix that runs on your own computer or server. This repository is the visual interface you actually see and interact with when you use Jellyfin. It's the web app you open in your browser to browse your movies, shows, music, and photos, and it also powers the mobile apps for Android and iOS. When you visit Jellyfin on your phone or laptop, you're using code from this project. It handles everything from displaying your media library and showing you trailers, to letting you play videos and manage your account. The interface needs to work smoothly on many different devices, a desktop browser, a phone screen, a tablet, and this codebase manages all of that. The project is built using standard web development tools: Node.js and npm, which are the common foundation for JavaScript-based projects. Developers can run it locally on their computer for testing, make improvements, and submit them back to the project. Since Jellyfin is open source and community-driven, anyone can contribute. The README also mentions that translations are especially easy to improve through a tool called Weblate, so if you speak another language, you can help make the interface available to more people around the world. This is a real project with active community support and regular releases. If you're running a Jellyfin server and something about the web interface could be better, maybe a button is in the wrong place or a feature is missing, improvements come from this repository.
