Hi,
 
 Because I noticed that in poky(master), the toaster has the ability to trigger a build command, and have
 the build executed.

    bitbake: toaster: add project main edit page

    This is the first commit on the project main edit page.

    At this point we have:
    * the default settings for a newly created project
    * the ability to add targets
    * the ability to trigger a build command, and have
    the build executed
    ......
 -----------------------------------------------------------
 
 So, I tried to use the new features of the toaster. But I don't know how .
 
 Is there anybody tell me where can I find the documentation how to use the new features?
 
 Best Regards,
