 Le projet vhélio est collaboratif (amélioration continue grâce aux contributions de tous). L’objet vhéliotech et le présent document constituent la première version définitive du vhéliotech, mais l'objet est voué à évoluer continuellement. Vous êtes invités à faire part de vos retours/expériences/propositions d’améliorations sur le [forum](https://communaute.vhelio.org) ainsi que sur le [dépôt officiel de la documentation](https://git.vhelio.org/vhelio/vheliotech-guide-de-montage)
