# Getting started

MediaContext helps adtech sellers research publishers, inspect source evidence and maintain account lists. Pilot access is invite-only. Use the application address supplied with your invitation. The application is awaiting hosted activation; the public marketing site is at [https://mediacontext.dev](https://mediacontext.dev).

1. Open your invitation with the invited email address. Sign in using an email magic link in the same browser and device where you requested it.
2. Select your assigned organization when prompted. A signed-in identity needs an active workspace membership before it can read workspace data.
3. Open **Database**. Search by domain or name and use the table filters to narrow your account set.
4. Open a publisher. Check its evidence source and observation date before treating a vendor, owner or score as current.
5. Star an account to add it to **Shortlist**, or use **Account Lists** to group accounts for a research task.
6. Open **Signals** to review matched changes. Use **Configure** to choose a scope and rule conditions.

Empty fields represent unavailable evidence. A publisher with no observed vendor is only an opportunity signal when the source actually observed the relevant page or field.
