Within a project, you can choose which screens to build your flows from. Not all screens are added to the flow by default — Zeplin leaves this up to you.
There are two ways to add screens to the flow:
Add a section of screens
You can add all screens in a section to the flow by clicking on the “Flow” button—on the top-right of the section.
Once you add a section to the flow, the flow button is highlighted in blue to indicate that this section is represented in the flow.
Add individual screens
You can also add your screens to the flow individually—right-click on a screen and select "Add to Flow" in the context menu.
You can select multiple screens and right-click to add them at once.
☝️ If you're on the Team, Organization, or Enterprise plans, only Editor roles or higher can create and modify flows.
