 NOTE! If you are using the RetroPie distribution, you have the option to install Skyscraper directly from the RetroPie-Setup script (*you need to update the script before installing it!*). Read more about all of that [in the RetroPie documentation](https://retropie.org.uk/docs/Scraper/#skyscraper).
 
-### Installation of Skyscraper on RetroPie and Programmable Completion
-This goes in the usual RetroPie stanza: Either run `sudo RetroPie-Setup/retropie_setup.sh` and folow the menus (_Manage packages_ -> _Manage optional packages_ -> then look for _Skyscraper_) or run `sudo RetroPie-Setup/retropie_packages.sh skyscraper`. This will also automagically install programmable completion (aka. bash completion) for the Skyscraper command line (see [command line completion](https://gemba.github.io/skyscraper/CLIHELP#programmable-completion)).

-_Qt5 is end-of-life by end of May 2025_: You can still use and compile Skyscraper with Qt5 with no restrictions, when your setup does not provide Qt6. However, if you have the option to use Qt6 I strongly recommend it, Skyscraper works well with Qt6. Use Qt6 especially when you use Skyscraper on a recent Linux distribution, macOS or Windows. In rare cases you may have to use `qmake6` instead of `qmake`. If you find a mismatch in the build scripts, please file an issue.
