Compodoc use Typescript AST parser and it's internal APIs, so the comments have to be JSDoc comments :
/** * Supported comment */
These ones are not supported :
/* * unsupported comment */ /* unsupported comment */ // unsupported comment
New lines are created inside a comment with a blank line between two lines.
/** * First line * * Second line */
The example below will produce only one line in the outputed documentation.
/** * First line * Second line */
