Salut {{first_name}}

Cool, vielen Dank für deine Bestellung. Ich habe deine Website soeben eingerichtet. Sie hat etwas Musterinhalt drauf, den du anpassen oder löschen kannst, so wie es für dich am einfachsten ist. Die Website ist noch gesperrt, sodass sie nur eingeloggte User sehen können.

{{links}}
Einloggen kannst du dich mit dem GRÜNEN-Login (das gleiche Login wie für den Chat, das Wiki, das CD-Tool etc.). Wenn du noch kein Login hast, kannst du dich selbst registrieren. Klicke dazu einfach auf 'Registrieren' und trage dich mit der folgenden E-Mail-Adresse ein {{email}}.

Eine Anleitung fürs Bearbeiten der Website findest du hier: https://docs.gruene.ch

Wie sieht es aus bezüglich Domain (Internetadresse)? Hast du bereits eine? Falls nein, kannst du beispielsweise bei Infomaniak eine kaufen: https://www.infomaniak.com/de/domains

Damit wir die Website auf deine Domain umstellen können, müsstest du als Nameserver folgendes eintragen:
    • ns1.cyon.ch
    • ns2.cyon.ch
    • ggf. weitere Zeilen löschen / leer lassen
Bitte melde dich vorgängig, damit wir die nötigen Änderungen auch bei der Website vornehmen können.

Unabhängig von der Domain, kannst du bereits jetzt beginnen, deine Inhalte einzufügen etc.

Herzlich,
Michael

Bonjour {{first_name}},

Cool, merci pour ta commande. Je viens de mettre en place ton site web. Il contient des exemples de contenu que tu peux personnaliser ou supprimer, selon ce qui est le plus facile pour toi. Le site est toujours verrouillé, de sorte que seuls les utilisateurs connectés peuvent le voir.

{{links}}
Tu peux te connecter avec le login VERT (le même login que pour le chat, le wiki etc.) Si tu n'as pas encore de login, tu peux t'enregistrer. Il suffit de cliquer sur "S'inscrire" sur l'écran de connexion et de saisir l'adresse électronique suivante {{email}}.

Des instructions pour l'édition du site web sont disponibles ici : https://docs.gruene.ch

Quelle est la situation concernant le domaine (adresse internet) ? En as-tu déjà un ? Sinon, tu peux en acheter un chez Infomaniak par exemple : https://www.infomaniak.com/fr/domaines

Pour nous permettre de passer du site web à ton domaine, tu dois entrer ce qui suit comme serveur de nom :
- ns1.cyon.ch
- ns2.cyon.ch
- si nécessaire, supprimer / laisser les lignes supplémentaires vides
Merci de nous contacter à l'avance afin que nous puissions apporter les modifications nécessaires au site web.

Quel que soit le domaine, tu peux déjà commencer à ajouter ton contenu, etc.

{{support}}

Cordialement,
Michael
