1. Copy/extract the "navigraph-navdata" and "navigraph-navdata-base" folders into your MSFS Community folder
2. Copy/extract the "Content.xml" file into the following directory (replace the old one if necessary):
* MSFS Steam version -> "C:\Users\<USERNAME>\AppData\Roaming\Microsoft Flight Simulator"
* MSFS Microsoft Store version -> "C:\Users\<USERNAME>\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache"
Note: Do not worry about replacing your old Content.xml file as "<Content>" entries are no longer used by MSFS starting with Sim Update 10. If you want to change the order of packages being loaded, you have to use "<Priorities>" entries now. Packages with lower priority numbers are loaded first, higher priority numbers last.
