There are lots of way to get tweets, they use twitter-api key, developer account, etc…
I’ll show you easy way to do that
Firstly, we need to add widgets.js from CDN
<script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
Then, add code block below
<a class="twitter-timeline" href="https://twitter.com/snowden" data-tweet-limit="5"
data-chrome="noheader noborders nofooter noscrollbar"> </a>
