Here is a sample addon.json:
{
"title" : "name",
"type" : "map",
"tags" : [ "build", "fun" ],
"ignore" :
[
"*.psd",
"*.vcproj",
"*.svn*"
]
}
You can just make a text file, rename it to addon.json (make sure you select "All Files" as the type, so you can change the file extension to.json), and insert this sample text. Thanks for watching!
