+# ChillBox
 
-Test
+> *A project by Pausetta.org, Simone Tesini, Francesco De Carlo, Leonardo Segala, Matteo Peretto*
+
+**ChillBox** is a web app that lets you create a shared radio station with a democratic voting system, so everyone gets to enjoy their favorite music together.
+Perfect for venues like swimming pools, cafés, or even lively parties.
+
+---
+
+## 🎵 Voting System
+
+Joining a ChillBox room is easy: users can either scan the QR code displayed on the host screen or use GPS to find nearby rooms.
+Hosts can set a location range, ensuring only people physically present can add or vote for songs.
+
+---
+
+## 📊 Ranking Algorithm
+
+ChillBox uses a smart ranking algorithm to decide what plays next. The score of each song is based on:
+
+* Votes from users
+* How recently similar songs (same genre or artist) have been played (less = better)
+* A bit of randomness to keep things interesting
+* A strong penalty for songs played too recently
+
+---
+
+## 👐 Hands-Off Experience
+
+ChillBox is designed to be almost entirely hands-free.
+Once the host sets up a room and optionally connects a screen or projector 
+(to show the current track, QR code, etc.), ChillBox takes care of the rest.
+
+ChillBox comes with built-in automatic moderation to keep the music fair and on-theme.
+
+* Users can’t vote for the same song multiple times.
+* A cooldown prevents users from spamming song requests.
+* Hosts can define preferred genres and overall mood, so no one can hijack your chill beach vibes with unexpected death metal.
+
+That said, hosts still have access to essential controls, like pause and skip, if needed.

+## Home screen
+We start here in the home page. 
+We can see this little radar animation, which means that the app is looking for nearby ChillBox rooms to join.
+It uses GPS for this feature.
+
+## Join room
+When we join a room, the server checks our location and checks if it's within a specified range.
+That way, you must physically be in the location to actually be able to add new songs
+
+## Talk about the host
+As you can see here (and hear) on the left, the host is already playing some music.
+Now i will add a song on the client side and it will pop up in the list.
