# How to use PromoStar to set up your bio page

> Link in Bio gives you a themed bio page on onlypromo.link. Add links, order them, switch each on or off, pick a theme, and publish.

Open **Link in Bio**, fill in your profile, add your links, pick a theme, and click **Publish**. Your page goes live on an `onlypromo.link` address.

## Steps

1. Click **Link in Bio** in the sidebar. On the **Content** tab, under **Who fans see**, click **Choose photo** to pick an image from your Media Library. Fill in **Display name**, **Handle (your public URL)**, and **Bio**, then click **Save**.
2. Under **Your links**, type a label and the destination address, then click **Add**. New links start behind the 18+ gate.
3. To edit a link, change its label or address in its row. It saves when you leave the field.
4. Drag a row to change the order. The page shows links in that order.
5. Click **Active** on a row to hide or show the link without removing it. To remove a link, click the bin icon, then **Delete**.
6. Open the **Design** tab. Pick one of the **Presets**, adjust **Background**, **Typography**, **Buttons**, and **Avatar**, then click **Save theme**.
7. At the top of the page, click **Publish**. The tag changes to **Published**. **Copy** copies your page address, **Open** opens the live page, and **Unpublish** takes it down.

On a wide screen, a preview beside the editor updates as you edit.

<Info>
  Your handle is part of your page address. If you change it, update the address anywhere you already shared it.

## How fan links work

Fans reach your page on an `onlypromo.link` address that PromoStar assigns, not on `promostar.app`. Your real destinations do not appear on the page or in its source. Each link a fan taps goes to a masked address, and PromoStar's server forwards it to the destination.

## Good to know

* Fans cannot open a draft page, and **Open** stays unavailable until you publish.
* Your handle takes lowercase letters, numbers, `-` and `_`.

## Where processing happens

PromoStar's public Link in Bio service serves your page. Once published, your photo, display name, bio, and link labels are public. Your destination addresses stay in PromoStar's database.
