I am having a lot of problems getting addons to work. First, there is no readme text file in the Zion scenery as you state (view the README file contained within the download). Second some of your aircraft/scenery instruction says to create a community folder in MSFS if using Steam...I have MSFS2020 loaded on my E drive but under appdata in C drive there is a MSFS2020 with a community folder.....I am really confused on how to do what with your addons.
Can U help me or is there a complete tutorial for MSFS2020 Steam users???
