+\begin{letter}{To \\ {{data.name}}}
+
+\opening{Dear  {{data.name}},}
+
+We are excited to introduce you to the new digital Netzbon using GNU Taler.
+In the enclosed brochure, you will find some introduction on how you can
+set up your business to accept e-Netzbon payments.
+
+This letter provides you with your personalized credentials to access your
+e-netzbon bank account and merchant backend. Please keep the password
+confidential as otherwise others might gain control over your e-Netzbon!  You
+are encouraged to set up second-factor authentication (via SMS or E-mail)
+before using the system.
+
+Your initial password is {\bf {{data.pass}}}.
+
+Using this password and the username {\tt {{data.id}}} you can log into
+your e-Netzbon bank account at {\tt https://bank.{{data.domain}}/}.
+
+Furthermore, we are happy to provided you with a GNU Taler merchant
+backend at {\tt https://backend.{{data.domain}}/instances/{{data.id}}/}.
+The backend is already configured to use your e-Netzbon bank account
+and uses the same password.
+
+You are encouraged to change the password (separately) in both systems.
+
+If you want to use a GNU Taler wallet (from {\tt https://wallet.taler.net/})
+you need to add e-Netzbon as a payment service provider before you can use it to
+invoice your customers. Scan the following QR code with your Taler wallet to do so:
+\begin{center}
+\qrcode[hyperlink,level=M,height=3cm]{taler://exchange/exchange.{{data.domain}}/}
+
+{\tt taler://exchange/exchange.{{data.domain}}/}
+\end{center}
+
+Our welcome package is including five QR code stickers which are pre-configured to
+create payments into your e-Netzbon bank account. Your personalized QR code looks
+like this:
+\begin{center}
+\qrcode[hyperlink,level=M,height=3cm]{taler://pay-template/backend.{{data.domain}}/instances/{{data.id}}/default}
+
+{\tt taler://pay-template/backend.{{data.domain}}/instances/{{data.id}}/default}
+\end{center}
+You can create additional QR codes or change the settings for this QR code
+in the merchant backend.
+
+Please sign the included terms of service and return them to us. If you want us to
+set up a Taler point-of-sale App, please complete the form from the introduction
+brochure and return that form to us as well.
+
+We hope your customers enjoy paying you with e-Netzbon!
+
+
+\closing{Best regards}
