Now that you have decided on the work you will be showing, you need to decide the best way to present them visually and contextually.
Behance's Chief Designer, Matias Corea, who has viewed thousands of online portfolios in his career mentions the following on the subject, “First, contextualise the project with a short paragraph. Add a title that makes sense and gives a hint of what this project is about. You want this to be quick reading — you need to be able to glance at it and understand what it’s about.”
Upon viewing the first image in your portfolio, you want the viewer to be interested enough to continue onto the remaining images in your work.
