Help for user-defined navigation data modification

Dear Sir,
I am a player of X-Plane12. Now I want to add some arrival/departure procedures of some airports that Navigraph does not have on the basis of the updated navigation data provided by Navigraph. I am writing this letter to ask your team for help on how users can customize adding navigation data.I would like to express my sincere gratitude.
Best wishes!

                                                               Xiao Chen

Hi,

Hope that helps
Richard
