title CSD Pool Miner - one-click installer
color 0a

REM ============================================================
REM  CSD Pool Miner - all-in-one installer for Windows.
REM  Double-click. It will:
REM    1. Detect your GPU (NVIDIA / AMD) or fall back to CPU.
REM    2. Install the Microsoft VC++ runtime via winget if missing.
REM    3. Download the matching prebuilt miner from GitHub Releases.
REM    4. Ask for your addr20 payout address once (and remember it).
REM    5. Start mining to the pool.
REM  Override detection:  install-csd-miner.bat nvidia ^| amd ^| cpu
REM  GPU drivers are NOT installed here - the GPU builds need your
REM  vendor driver already present; otherwise use the cpu build.
