An opportunity is what people are approved to, so almost every visibility question in Vome traces back to how you built one. The shape you choose here is also the hardest thing to change later, because reversing it means moving each opportunity by hand.
This page gathers the articles that settle those decisions. They live in the Setup Guide section of this knowledge base, and cover what to choose and why. The rest of this section covers how to do it.
An article in this knowledge base can only be filed in one section, so the Setup Guide holds them and this page links to them rather than repeating them. You will find them under For administrators, in the Setup Guide, stages 1 and 4.
The how-to articles: building an opportunity step by step, cover photos and descriptions, visibility, recruitment workflows and publishing. Read the decision articles above first if this is your first opportunity, then come back here.
