what does the Making a Mod tutorial mean by this?

it says "Upgrades are one of several Big Features in TMT, and most of them work the same way. Most of what applies to upgrades applies to milestones, buyables, etc. To add upgrades to your layer, after all of the other features, add a comma to the end of the last one, and then put:"

the text that i want to know the meaning of is in bold

Your features should be separated by a comma, like this:

upgrades: {
    // feature code here
}, // <- comma here
buyables: {
    // feature code here
}, // <- comma here
challenges: {
    // feature code here
}, // and so on…

Also for the record please go to (https://galaxy.click/forum/category/gamedev)[#gamedev] for help regarding game development

i am very confused
where do i put the upgrades? here is my code

("p", {
    name: "Multiply", // This is optional, only used in a few places, If absent it just uses the layer id.
    symbol: "M", // This appears on the layer's node. Default is the id with the first letter capitalized
    position: 0, // Horizontal position within a row. By default it uses the layer id and sorts in alphabetical order
    startData() { return {
        unlocked: true,
		points: new Decimal(0),
    }},addLayer
    color: "#df4920",
    requires: new Decimal(10), // Can be a function that takes requirement increases into account
    resource: "Multiplacations", // Name of prestige currency
    baseResource: "points", // Name of resource prestige is based on
    baseAmount() {return player.points}, // Get the current amount of baseResource
    type: "normal", // normal: cost to gain currency depends on amount gained. static: cost depends on how much you already have
    exponent: 0.5, // Prestige currency exponent
    gainMult() { // Calculate the multiplier for main currency from bonuses
        mult = new Decimal(1)
        return mult
    },
    gainExp() { // Calculate the exponent on main currency from bonuses
        return new Decimal(1)
    },
    row: 0, // Row the layer is in on the tree (0 is the first row)
    hotkeys: [
        {key: "p", description: "P: Reset for prestige points", onPress(){if (canReset(this.layer)) doReset(this.layer)}},
    ],
    layerShown(){return true}
})

so where do i put the upgrades: { }, ???

staff edit: fixed markdown c:

There are many places you could put the upgrades, but the easiest place would be after the layerShown, like so:

    [...]
    layerShown(){return true},
    upgrades: {
        // upgrades go here
    },
})
