Pulse for PowerPoint - Add-in Installer
========================================

WHAT THIS IS
    A PowerPoint add-in that drives your live Pulse event from your slideshow,
    so attendees' phones, polls, quizzes, and the exit survey follow the slide
    you're on. It loads its task pane from nowpresenting.net and updates itself,
    so you install it once.

------------------------------------------------------------------------
INSTALL - WINDOWS
    1. Extract this whole archive to any folder.
    2. Double-click  Install.cmd
    3. Approve the one Administrator (UAC) prompt.
    4. Open PowerPoint > Insert > My Add-ins > SHARED FOLDER tab >
       Pulse for PowerPoint.
    5. Pair with your Pulse event using the 6-character code.

    Advanced: run  Install-PulseAddin.ps1  directly from PowerShell.
      Flags: -ShareName, -InstallDir, -NoCacheClear, -Uninstall

    What it does:
      - Copies the add-in to C:\ProgramData\PulseForPowerPoint (a stable
        location, so you can delete this extracted folder afterward).
      - Publishes that folder as a read-only network share (Windows requires
        an add-in "catalog" to be a network share).
      - Registers the share as a Trusted Add-in Catalog for your Windows user.
      - Clears the Office add-in cache so the latest version loads.
    Re-running it is safe and is also how you UPDATE to a newer release.

    Uninstall: double-click  Uninstall.cmd

------------------------------------------------------------------------
INSTALL - MAC
    1. Extract this whole archive to any folder.
    2. Double-click  Install-Mac.command
       (If macOS blocks it the first time: right-click > Open, or run
        "bash Install-Mac.command" in Terminal.)
    3. Quit and reopen PowerPoint.
    4. Insert > My Add-ins > Pulse for PowerPoint.
    5. Pair with your Pulse event using the 6-character code.

    What it does:
      - Copies manifest.xml into PowerPoint's per-user add-in folder
        (~/Library/Containers/com.microsoft.Powerpoint/Data/Documents/wef).
      - Clears the add-in cache so the latest version loads.
    Re-run any time to update. Uninstall: "bash Install-Mac.command --uninstall".

    (The Mac has no network-share / admin machinery - that is Windows-only.)
