Hi there this is really blowing my mind.
I just start with a fresh clean Native Install of Open edX, an d trying to publish my first course.
According to the documentation of this link, Subjects and more information can be added to the course.
Unfortunately I cannot find how to add such information or how to activate it.
I have already activated the search engine and it works well, but the subject I do not know where to add it and I require it to classify the courses on my platform.
