By clicking the build button for particular platform the signageOS cloud services will prepare the zip file with your built application. Just click the green Download application link under the platform name to download that zip file after the build finished.



Once you are done with the current development and you want to use your code in production we strongly recommend to Publish your Applet version.

So it makes sure anytime you push this version of your Applet into the device it will be the same.
