save the edit to a local file

[fatih0057]

hello SteveCline
First of all I apologize for my english.
I found your work very successful and I want to use it, but unfortunately, I am not quite enough in software.

I have a geojson map that I am using and I want to edit it from the admin panel.
How can I save my current file when I add my geojson file to this work and say save the edit.
Thanks in advance forever.
