First time handing over designs and assets to developers


Hi, it’s my first time handing over my designs to a development team who are using React Native to develop an app. How many image files do I need to send? I just downloaded Zeplin and noticed that it extracts 5 png files. If I use these do I need to rename them? Also, I want to make sure I give them everything they need so if you could list the assets you send with your designs that would be great. Any help on this would be greatly appreciated.


Welcome on board Cydney.

@StudyOfPeople and @tara_lee_york are familiar with Zeplin. Hopefully they can advise you.


Hi @crusch00!

I’m not sure if you’re using Photoshop, or Sketch, but here are two handy videos that will show you how to mark layers as assets (from within Photoshop, or Sketch):

Once you’ve done that, and exported your design to Zeplin, it does a bunch of the heavy lifting for you. You can then go through and create a color palette fairly easily, which is covered in this YouTube video:

That should be all that you have to do. From that point, your developers should have all measurements, colors, and assets that they’ll need once you invite them to the project.

Hope that helps!

p.s. I’m happy to answer any follow up questions you might have.


Thank you so much @startlaunch!

The videos were so helpful. I really appreciate you taking the time to answer my questions.
