2. Create a link. This can anything, like the word PORTFOLIO or a reactangle with PORTFOLIO written in it.
3. Go to "inspector". Find the menu that deals with hyperlinks (a hyperlink is a word, a shape, that has a go-to address attached, so when you hover your cursor, you get the "this is a link"-behavior, and when you click, it takes you to the other page). It's a blue dot with a white, curved arrow in it.

Then choose from the menu. Connect to "external page". Put in the web address of your portfolio, e.g. JohnFrankensteinmonsters.com/terrorportfolio.
That's it.
Try it out. Click "enable hyperlinks", click the link, and your browser will launch and get you to the portfolio page.
HOW TO SET UP YOUR LIGHTROOM GALLERY
Just create a collection, click the web module on the right upper corner.
In the web module, choose the viewer you like, adjust the settings.
Upload.
You can use the uploader within lightroom.
Let's say your website is JohnFrankensteinmonsters.com.
Then you create your page by typing into the uploader as destination address: JohnFrankensteinmonsters.com/portfolio.
In your public html folder on your website a new page with this name is created through uploading.
When you now click the hyperlink, it'll carry you to the page.
So, through uploading you, at the same time, create the page address within your domain (domain is the name of your site, like
www.JohnFRankensteinmonsters.com) AND upload the content.
Good luck.
