# Quick start for network managers: create the supply side

**Goal:** in about five minutes, have the supply-side chain — a site → *Homepage* → a 300×250
placement — saved, with a size that matches the banner from Stage 1.
It is one stage of the [network quick start](https://epom.com/ad-server/docs/start/quick-start-network.md), whose prerequisites, caveats and fix-it table apply here too.

## Steps

### Stage 2 — create the supply side (site → zone → placement)

1. Go to **Account → Publishers** and click **New site**. Fill in **Name**, optionally pick a
   **Category** (required only where your network demands it), keep **Inventory type** =
   *Website*, and enter the **Site URL**. Click **Save**. Success: a "Site saved" toast and the
   site's edit page.
2. With the site selected, click **New zone**. A zone is just a named group of placements —
   give it a name like "Homepage" and save.
3. With the zone selected, click **Add new placement...** — a menu of the placement types you
    may create opens. Pick **Site Placement** to match the banner.
4. On the **Create new placement** page fill in **Name** and set **Size** to the *same* size
    as your banner's ad unit (e.g. the 300×250 ad unit). Click **Save**. Success: you land on the
    placement edit page, which shows the placement's cards — **Ad tags & API** among them for a
    role that holds a tag permission.
