Adding a 2nd portfolio and changing portfolio names

Hello. I’d like to add a 2nd portfolio to this theme. I remember seeing a topic about this on the old forum, but now I can’t find it so here goes.

1) Currently I have just the default one portfolio on a page /portfolio/. Ultimately what I want is to have 2, one on /portfolio/video/ and another on /portfolio/web/.

2) So I know I need to add a 2nd portfolio. I remember it being duplicating some code in the functions.php, but I don’t remember exactly which ones. Can you tell me which?

3) From that point, I don’t know if I need to (or should) modify the portfolio slug to something unique per each portfolio type. Thoughts?

4) I’m assuming that an additional page template would have to be created too for the new portfolio. Am I right on that? If so, how?

I think that’s it, but I may be missing something. Please advise. Thanks.

Micha
