"Make me a Upgrade system with instructions on how to use"

To create an upgrade system, you will need to create a shop GUI where players can purchase upgrades using in-game currency. Here's an example script for a simple upgrade system:

-- server script for shop GUI 
local shopGui = game.Players.LocalPlayer.PlayerGui.ShopGui
local playerData = game.Players.LocalPlayer:WaitForChild("leaderstats")

local function purchaseUpgrade(upgradeName, upgradeCost)
    if playerData.Coins.Value >= upgradeCost then
        playerData.Coins.Value = playerData.Coins.Value - upgradeCost
        -- add upgrade to player's inventory or apply upgrade to player's character
    else
        -- display error message to player
    end
end

shopGui.UpgradeButton1.MouseButton1Click:Connect(function()
    purchaseUpgrade("Upgrade1", 100)
end)

shopGui.UpgradeButton2.MouseButton1Click:Connect(function()
    purchaseUpgrade("Upgrade2", 200)
end)

-- client script for displaying player's inventory 
local inventoryGui = game.Players.LocalPlayer.PlayerGui.InventoryGui
local playerData = game.Players.LocalPlayer:WaitForChild("leaderstats")

playerData.Bag.Changed:Connect(function(newBagValue)
    inventoryGui.InventoryText.Text = "Inventory: " .. newBagValue .. "/3"
end)

-- To use the upgrade system, players can open the shop GUI and click on the upgrade buttons to purchase upgrades. Upgrades can be applied to the player's character or added to the player's inventory. The player's inventory can be viewed by opening the inventory GUI.
