 ## Overview
 Galène is a videoconferencing server that is easy to deploy (just copy a few files and run the binary) and that requires moderate server resources. It was originally designed for lectures and conferences (where a single speaker streams audio and video to hundreds or thousands of users), but later evolved to be useful for student practicals (where users are divided into many small groups), and meetings (where a few dozen users interact with each other).

 ## Vue d'ensemble
 Galène est un serveur de visioconférence facile à déployer (il suffit de copier quelques fichiers et d'exécuter le binaire) et qui nécessite des ressources serveur modérées. Il a été conçu à l'origine pour les conférences (où un seul orateur diffuse l'audio et la vidéo à des centaines ou des milliers d'utilisateurs), mais a ensuite évolué pour être utile pour les travaux pratiques des étudiants (où les utilisateurs sont divisés en plusieurs petits groupes) et les réunions (où un quelques dizaines d'utilisateurs interagissent les uns avec les autres).
