Add description for each product category? Edit a specific category page?

What's the best way to add a text description for each product category, to be displayed when the user navigates to that category? For example:

On /shop/large-widgets I want it to say:
"Large Widgets: These widgets measure 48 inches and are perfect for outdoor use."

But on /shop/small-widgets I want:
"Small Widgets: These widgets measure 24 inches and are recommended for indoor use."

So far I haven't found a great way to edit individual category pages in this way. What's the best practice?

Can you share link to large - small widgets page? We can check easier.

Hello, I have the same question. What is the solution for this?

Also, the content we add on "Shop" page will appear on each and every category page.

So can we add different content for "/shop" and "/shop/category"?

Perhaps the following post will point you in the right direction.

The whole thread covers some variations on the technique.

I don't know if it will work for you as I have no information about your site.

@creedon I have added script part in header, Script is not working "$ is not defined. "

@SAUMIL

Did you follow the following step?

Add the following to Settings > Advanced > Code Injection > HEADER. 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

@creedon its working now thanks
