Why is my JSON not working for my sublime text settings?

I do not code in JSON and I'm trying to configure some settings for Terminus on Sublime Text 3. Why isn't my code working? I suspect it has something to do with the colons because they appear to be a different color than on the README page. Thanks in advance!

[
    "default_config": {
        "linux": null,
        "osx": "PowerShell",
        "windows": null
    },

    "preserve_keys" : [
        "ctrl+k",
        "ctrl+p",
        "ctrl+z",
        "ctrl+c",
        "ctrl+v",
        "ctrl+x"
    ],

    "theme": "default"
]

Solution

You should replace [ ] with { } like that:

{
    "default_config": {
        "linux": null,
        "osx": "PowerShell",
        "windows": null
    },

    "preserve_keys" : [
        "ctrl+k",
        "ctrl+p",
        "ctrl+z",
        "ctrl+c",
        "ctrl+v",
        "ctrl+x"
    ],

    "theme": "default"
}

If you want to store data using key value, you have to use { }. If you want to store data in json as an array, you have to use [ ]. This is the difference which made you an error.
