How do I integrate my game with Steam?

Hello, I'm new here and I'm about to release my game on Steam.

But I have no idea of where to start the integration.

Does anyone have a tutorial, or could help me with that? What should I do? I have no idea of where to start.

Also, a .capx with an example of how to set-up achievements would be highly appreciated.

Thank you very much,

All the support for Steam with construct is provided here:

This is usually rather iffy with the build of NWjs you are using.

From the look of your profile though (you don't have the badge), you can't export using NWjs, so you'll need to purchase a license first.
