You can find HelpCase option access in the menu item "Tools".
A documentation built in HelpCase is always associated with a Scriptcase project. During the new Manual creation you don't have to select the project, because it is already selected according to the project which ScriptCase is accessing at this very moment.
Creating a new documentation
Once you create your HelpCase, the screen below will be displayed by ScriptCase so you can begin documenting the features and descriptions of your project.
