I'm new to Qt and the Qt Creator IDE and I was able to download the source code from the "assets" folder. When I open the .qmlproject file for chapter 01 in Qt Creator I get a warning about missing .user file created "by this instance of Qt Creator".

I can see that the .user file has some kind of settings for the IDE. Should this settings file be spread between computers?

Anyhow, this lead to this bug report on improving the very first note.

The source code of this chapter can be found in the assets folder.

The source code of this chapter can be found in the assets folder. Start Qt Creator and
open the showcase.qmlproject file. Press "yes" if Qt Creator warns you about missing
.user file (created by the current instance of Qt Creator).
