Here we link you to some tutorial resources for aiida-fleur and related topics. In general you find hands-on tutorial material under https://github.com/JuDFTteam/judft_tutorials and in the examples folder of the aiida-fleur package (the examples lack sometimes behind).
If you are not familiar with the basics of AiiDA yet, you might want to checkout the AiiDA youtube tutorials. The jupyter notebooks from the tutorials you will find here on github, where you can also try them out in binder. Virtual machines for tutorials and tutorial manuals you find here.
