+
+* You need to upload a **SignatureTemplate** to the **[A-Trust](https://www.a-trust.at)** service. Uses `AddTemplateATrust` start in the `ATrustDemo` process of `a-trust-connector-demo` project.
+
+   When uploading successfully, **A-Trust** returns `templateID` and sets it in project Variables - `TemplateId` value in the `Configuration/variables.yaml`.
+
+* An example **SignatureTemplate** in CMS: `cms/Templates/tempsiegel1`.
+
+
+
+## Setup
+
+Before any signing interactions between the **Axon Ivy Engine** and the **A-Trust HandySignatur** services can be run, they have to be introduced to each other. This can be done as follows:
+
+1. Register an **A-Trust HandySignatur** account: https://www.a-trust.at/en/handy-signatur/handy-signatur-activation/
+
+2. Create an **A-Trust Signatur-Box** **[here](https://www.a-trust.at/en/handy-signatur/signaturbox)** and then get a new `API key` with the `Endpoint URI` web service.
+
+3. Open the `Configuration/variables.yaml` in your Designer and paste the below code with your `APIKey`, `TemplateId`, `EndpointUri`
+
+   ```
+   Variables:
+     # Custom variables of ATrust Handysignatur API
+     ATrust:
+       # API Key for "A-Trust Handysignatur API"
+       APIKey: 'your API Key'
+
+       # The endpoint uri of A-Trust Handysignatur Signatur-box webservice
+       EndpointUri: 'your Endpoint URI'
+
+       # The ID of the signature template to be used.
+       TemplateId: # your TemplateId with number format, e.g: 1
+
+   ```
+
+4. Save the changed settings.
