Right markdown code for link to category page?

I have just started with hugo.
Now have the problem that I want to insert in a post, a link to a category page.
What must the markdown code look like for a link? Link are http://localhost:1313/categories/testpostings/


There is doubtless a more Hugo’y way but perhaps simply use /categories/testpostings as the link since that will work no matter what the base URL.

Thanks, this was it. Before i have add to many things.

No problem, welcome to Hugo. I’ve not long started myself. It is a great tool though and a pleasure to use.
