Adding Twitter feed

Hello

I am hoping to add a Twitter feed to a Web page, but can only find an outdated article on how to do it.

I am in Twitter at the moment and can see this (please see attached).

The feed will be placed in a web page similar to this (on the right and underneath 'welcome to my site'):

home

and with a similar colour scheme.

what should I be pressing on the Twitter site, please?

Thanks.
