  CHEA 4K DOWNLOADER  —  v1.0.0
  YouTube video + audio downloader (up to 4K/8K)
========================================================================

WHAT THIS IS
------------
A small desktop app for downloading YouTube videos and audio in high
quality. Paste a link, pick video or audio and a resolution, choose a
folder, download. Self-contained — nothing to install.

Made by Chea Studios. Shared directly with you; not sold or published.


HOW TO RUN
----------
1. Unzip "CHEA-4K-Downloader-v1.0.0.zip" to any folder (e.g. Desktop).
2. Open the "CHEA 4K Downloader" folder.
3. Double-click "CHEA 4K Downloader.exe".

Keep the whole folder together — the app needs the "_internal" folder
next to the .exe. Don't move the .exe out on its own.


FIRST-RUN WARNINGS (this is NORMAL — the app is not signed with a paid
certificate, so Windows shows a caution the first time)
------------------------------------------------------------------------
• "Windows protected your PC" (SmartScreen):
      Click "More info"  →  "Run anyway".

• Windows 11 only — "Smart App Control blocked an app that may be
  unsafe": Windows 11's strictest mode blocks all unsigned apps.
  If you see this, turn Smart App Control off:
      Windows Security → App & browser control →
      Smart App Control settings → Off
  (There is no per-app exception; this is the documented path.)

You only see these once. They appear because the app is new and
unsigned — not because anything is wrong with it. See "IS THIS SAFE"
below.


IS THIS SAFE?
-------------
Yes. Two things you can verify yourself:

1. VIRUS SCAN — this build was scanned with Windows Defender:
   "found no threats." You can re-scan it yourself: right-click the
   folder → Scan with Microsoft Defender. You can also upload the .exe
   to virustotal.com for a 70-engine check.

2. FILE INTEGRITY (checksum) — verify the download wasn't altered.
   Open PowerShell in the folder with the .zip and run:

      Get-FileHash .\CHEA-4K-Downloader-v1.0.0.zip -Algorithm SHA256

   The result must EXACTLY match the SHA-256 in the file
   "CHEA-4K-Downloader-v1.0.0.zip.sha256" (shipped alongside the zip).
   If it matches, the file is byte-for-byte what was sent. If it does
   NOT match, do not run it — re-download.


WHAT IT NEEDS
-------------
• Windows 10 or 11 (64-bit).
• Nothing else — yt-dlp, deno, and the runtime are bundled inside.
  (ffmpeg: used for merging/transcoding. If a merge fails, install
  ffmpeg and add it to PATH, or ask Chea Studios for the ffmpeg build.)


NOTES
-----
• Downloads go to the folder you choose; files are named cleanly.
• For personal use. Respect YouTube's Terms of Service and copyright —
  download only content you have the right to.
