 ## Examples
+
 Start with a fresh set of configuration files:
+
 ```shell
 ./bin/mid-client.sh -init 
 ```
 
 Get the profile information for a particular phone number (MSISDN) that your application provider is controlling:
+
 ```shell
 ./bin/mid-client.sh -profile-query -msisdn 41790000000 
 ```
 
 Get the same profile information using a particular configuration file and the SOAP interface of Mobile ID:
+
 ```shell
 ./bin/mid-client.sh -profile-query -msisdn 41790000000 -config local-config.properties -soap 
 ```
 
 Request a digital signature to a particular phone number (MSISDN), in sync mode:
+
 ```shell
 ./bin/mid-client.sh -sign -msisdn=41790000000 -geofencing -lang=en -dtbs "Do you want to login?" -sync  
 ```
 
 Request a digital signature to a particular phone number (MSISDN), in async mode (this is the default mode) and with signature receipt:
+
 ```shell
 ./bin/mid-client.sh -sign -msisdn=41790000000 -lang=en -dtbs "Do you want to login?" -receipt -req-timeout 120  
 ```
 
+Request a digital signature to a particular phone number (MSISDN), in async mode (this is the default mode) and with app2app service:
+
+```shell
+./bin/mid-client.sh -sign -msisdn=41790000000 -lang=en -app2app="myapp://example" -req-timeout 120  
+```
+
 Request a Mobile ID Serial number based on particular phone number (MSISDN), in async mode:
+
 ```shell
 ./bin/mid-client.sh -get-mid-sn -msisdn=41790000000 -rest
 ```
 
 Note: when working with arguments that have values (such as _-msisdn_) you can pass the value either as the next argument:
+
 ```shell
 ./bin/mid-client.sh -sign -msisdn 41790000000
 ```
+
 or in the form _name=value_:
+
 ```shell
 ./bin/mid-client.sh -sign -msisdn=41790000000
 ```
+
 Please note that the _-dtbs_ argument is a bit more special, as it will most likely contain spaces, so either the entire name=value
 construct is enclosed in double quotes or, if you use the name<space>value form, then the value is enclosed in double quotes:
+
 ```shell
 ./bin/mid-client.sh -sign -msisdn=41790000000 -dtbs "Do you want to login?"
 ./bin/mid-client.sh -sign -msisdn=41790000000 "-dtbs=Do you want to login?"
