JB's VIDEO DOWNLOADER  -  QUICK START
=====================================

Everything runs on your own computer. Nothing is uploaded.

TO START
--------
  Windows :  double-click  "Start - Windows.bat"
  macOS   :  double-click  "Start - Mac.command"
  Linux   :  double-click  "Start - Linux.sh"  (or run it from a terminal)

The first launch takes about a minute to set itself up (it also includes
video tools, so there is nothing else to install). Your web browser then
opens automatically at  http://localhost:9321
Keep the small black window open while you use the app; close it to quit.

YOU MAY NEED PYTHON (a free, one-time install)
----------------------------------------------
If a start file says Python is missing, it opens the download page for you.
Install Python 3.9+ from  https://www.python.org/downloads/  and start again.
On Windows, tick "Add Python to PATH" during install.


FIRST LAUNCH: APPROVING A FREE APP (one time only)
==================================================
Because this app is free and not code-signed, your system shows a one-time
safety prompt the first time. This is normal and only happens once.

macOS  -  If you see "Apple could not verify ... Move to Bin":
  Easiest (no warning): open the Terminal app, type:  bash
  then a SPACE, then drag "Start - Mac.command" into the Terminal window and
  press Enter. It runs and clears the flag, so double-click works next time.

  Or without Terminal: click Done, open System Settings > Privacy & Security,
  scroll to Security, click "Open Anyway" next to Start - Mac.command,
  enter your password and click Open. One time only.

Windows  -  If "Windows protected your PC" appears:
  click "More info" then "Run anyway". One time only.

Linux  -  If double-click does not run it, open a terminal in this folder and
  run:  ./"Start - Linux.sh"
