Hi Arthur!

That is because jQuery is a long list of methods prewritten in javascript for you to use. It is already downloaded on the treehouse workspaces and the code challenges. If you are planning on writing it on a text editor, you will need to download it or or link it with a cdn.

If you download it you will have to keep it with your other project files and link it with a script tag, and then in another script tag you will write your jquery code.

If you link it with a cdn, you do not need to download it. You will just put a link in a script tag just like you would if you had downloaded it, but instead of the file, you would put a link to a file on the web.

Jquery download

There is a big download button, and if you scroll down you will see the google cdn, microsoft cdn, etc.

Hope this helped!

Thanks! :)

Thank you! That was much more of a complex process than I expected. But in the end I figured it out.
