Making text fit in circles

This may do it https://fittextjs.com/

I downloaded the plug-in but no change.

How did you install it?

I installed the plug-in through wordpress. Should I follow the instructions on the site instead?

I’m not sure what you did, sorry.

I went through the plug-in’s page and installed the fittext plugin and activated it.

It’s not a WordPress plugin, see this page https://github.com/davatron5000/FitText.js

Ah okay. Where in the theme should I paste the script? I apologize in advance, im not very familiar with plug-ins.
