I would like to create a new journal format for Quarto. I found the documentation page on how to do this, which says you start by running
quarto create extension journal
In your terminal. However, when I run this command I get the error
ERROR: Unknown command "create". Did you mean command "render"?
I have RStudio version 2023.03.0+386 (2023.03.0+386) and Quarto version 1.0.37. Do I need to update one or both of these things? Any other suggestions?
