# Créer un site

Nécessite `sites:write`. Ne coûte aucun crédit. Rien n’est publié.

Le site est créé à partir du modèle de démarrage, un projet Astro destiné aux petites entreprises, avec des services, un blog dont les articles indiquent à quels services ils se rapportent, ainsi que des informations sur l’entreprise. Il s’agit d’une base à adapter : un site supprime ce dont l’entreprise n’a pas besoin et ajoute ce qui lui est utile. `description` et `locale` sont renseignés dans les informations de l’entreprise.

La première génération démarre automatiquement. Consultez le [modèle de contenu](/docs/api/content/model) lorsque cette génération est `ready`, puis renseignez le contenu.

Un nouveau site est un brouillon : vous pouvez le modifier gratuitement et le partager au moyen de liens d’aperçu. Il peut être publié une fois le forfait Site activé. Un espace de travail peut contenir jusqu’à 10 brouillons (25 après l’achat d’un forfait Site ou de crédits) ; les Sites ne sont pas comptabilisés. Toute création au-delà de cette limite est refusée avec une erreur `409 conflict` qui précise la limite.
