Terminal problem: "-bash: $: command not found" I'm trying to start learning Swift and when I use the terminal line 

$ export PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:"${PATH}"

it gives me 

-bash: $: command not found

What should I do?
I have literally no experience with Terminal and just following the steps from Installing Swift.
$  represents the standard shell prompt and is usually used to show that the commands need to be entered in Terminal. So you only need to enter the part starting with export.
