Exporting artboards from a Sketch design to Zeplin is quite straightforward. 🚀 To be able to export designs, you need to download the desktop app.
Select any layer/artboard in your Sketch file.
Press ⌃⌘E or use the menu up top “Plugins > Zeplin > Export Selected…” to start export process.
☝️ It's sadly not possible to import Sketch files directly into Zeplin since Zeplin works with a plugin. If you don’t see the plugin in the Sketch menu, you can install it here.
Zeplin shows the file location on the right panel of the screen if you're the user who exported that screen and you're using the same machine that you used to export. You can directly open the design file in Sketch by clicking on the file name.
