## How to Inject

Follow these steps precisely for a successful injection:

<Steps>
  <Step title="Prepare Launcher">
    Run the desired game launcher.
  </Step>

  <Step title="Load the Cheat">
    1. Run the Proofcore loader as **administrator**.
    2. Log in using your website credentials (email and password).
    3. Select **Call of Duty** and press **Load**.
  </Step>

  <Step title="Launch Game">
    Wait for the loader to close itself. You **must run Call of Duty** within **2 minutes** after the loader has closed.
  </Step>

  <Step title="Open Menu">
    Once you are in-game, open the menu by pressing the **Insert** key.
  </Step>
</Steps>

<Note>
    It can take up to 5 minutes for the menu to show up. If it still doesn't show up, the injection did not succeed or you haven't prepared your computer or game correctly. Refer back to the **System Preparation** guide.
