**ADDING YIELD PARTNER**

1. Open [MAX > Mediation > Manage > Ad Units](https://dash.applovin.com/o/mediation/ad_units/) in the MAX dashboard.
2. Select the Ad Unit of type **MREC** to which you want to add **ADSTER.TECH** as a custom adapter.
3. Select **ADSTER.TECH** from custom network menu to **Enable** and enter the information for each placement. 

   ```json
   App ID = Leave it blank (its optional)
   Placement ID = "adster_banner_300x250_10"
   eCPM: 10 (in USD)
   Custom Parameters = {"placement_id":"adster_banner_300x250","yield_group_bid_price_range":"10.0-10.0"}
   ```
4. Contact your account manager to see what values you need to set for the **final list of production setup (Placement ID**, **Custom Parameters** and **CPM Price)**.
