As explained here: https://github.com/jsdoc2md/jsdoc-to-markdown/wiki/How-to-document-TypeScript#jsdoc-comments-disappear
I should put a javascript code (also put a number) before and after every type definitions (type or interface, it acts at the same).
But this is really an horrible workaround!
I'm looking for a solution for that. Do you have any news about it?
Thanks.
