 Questionnaires
 --------------
 This section is where whistleblowing questionnaires could be created and managed.
-The system with the basic configuration completed with the initial Platform wizard is configured with a single Default questionnaire not editable and pre-associated to the Default Context.
 
-Depending on your project needs here you could create additional Questionnaire for each of your different contexts.
+By default the software implements a Default Questionnaire with a single Step and the following three questions:
+   One question "Short description" of type "Multi-line text input" enabling whistleblower to provide a short summary of the fact reported;
+   One question "Full description" of type "Multi-line text input" enabling whistleblowers to describe the fact reported in detail;
+   One question "Attachments" of type "Attachment" enabling users to load one or more attachments.
 
-This section is furtherly divided in:
-   1. Questionnaires
+The system with its basic configuration completed with the initial Platform wizard is also already configured with this Default Questionnaire pre-associated to the Default Context.
 
-   2. Question templates
+Depending on your project needs you could create specific questionnaire for each of your different submissions' contexts.
