How do you add tools on roblox

(way better explained answer)
There is a tab called "roblox studio" press it. If a white bar with pictures pops up click the button that has the roblox sign with a "+" symbol on it. if another bar comes up with a bar and a arrow pointing down next to it (in the new bar).now press the arrow.press "free models" then in a white search bar search the tool you want. there might be many varities tools you wanted... click the one you want. it will be placed on your map automatically. Hope this helped!!!
