About article classification

hi everyone. I’ve been using Ghost CMS for nearly 3 months now, and the features have been continuously updated as my site grows. Recently I wanted to add a menu for categorizing articles by tags on my own site, and I seem to recall seeing a related post about this in the community before, but I can’t find it now. Can anyone help me with this or provide a tutorial link?

My site version is 5.59.1 and I’m using the default Casper theme v5.6.0.
