I am reading a codebase written some times ago, and the comments are embedded with HTML tags such as
* Class Description
* List of configurations
I assume this is Java code.
These are JavaDoc comments (they start with
/**). You can't see them formatted in the actual Java editor.
You can open the 'JavaDoc' view (use 'Window > Show View > Javadoc') which will show you the formatted JavaDoc for the currently selected item in the Java editor.
