# Steam key activation
In order to activate your Product Key on Steam, first, you need to install the Steam Client Application. You can download it [here](https://store.steampowered.com/about/).
After you download and launch the app, follow these steps:
1. Sign in with your Steam logins, and select **ADD A GAME** as shown in the picture below. You will get 3 options, from which you need to select the **Activate a Product on Steam** option.
2. After the Product Activation window pops up, select **Next**.
3. Select the **I Agree** option since Steam Subscriber Agreement needs to be agreed upon in order to continue.
4. Copy the Game Key and paste it in the Product Code field, then click **Next**.
