If you already have a flow project created on Botmock, you can easily create a mock board from it. To do this, first you need to create a Journey in your flow project. To learn how to create a journey, check out this article.
Once you created a journey, click the Journey menu on the left side of the Flow Editor.
From the slide-out window, select the Export link.
Click the button Save As Mock Project to create a new mock project with the selected journey flow.
