The short answer: describe the network you want in plain language, and ATRIUM builds it. There is no code, no server setup and no app development involved.
Step 1 — Write a good prompt. This is the only step that really rewards effort. Say who the community is for, what people will do there, and what makes it different. "A network for freelance architects to share project photos, find collaborators and run paid workshops" produces a far better result than "a social network."
Step 2 — Review what comes back. You'll get a working platform, not a mockup. Walk through it as a member would: sign up, post something, send a message, look at it on your phone.
Step 3 — Make it yours. Branding, naming and structure are yours to set. This is where your community stops looking like a template.
Step 4 — Connect the outside services you need. Storage provider, SMTP for outgoing email, payment gateway, and the providers behind video, audio and SMS are all configured in the admin panel. You choose the vendors and you're billed by them directly.
Step 5 — Write your rules before you invite anyone. See the community setup guide below. This is the step people skip and regret.
Step 6 — Invite a small first group, not everyone. An empty network with 500 invited strangers fails. Twenty engaged people who post on day one succeed.
How members sign in: with their UIID. No password to create, no account to manage. Members own that identity — it isn't owned by your network, and it stays with them if they leave.
