+# Check Availability Script
+
+An experimental script that check if the downloaded videos are still available on YouTube.
+
+See the reasoning in: https://github.com/TheFrenchGhosty/TheFrenchGhostys-Ultimate-YouTube-DL-Scripts-Collection/issues/65
+
+This scripts only supports YouTube, running it on a folder that contain videos from other source will just make those videos appear as not available on YouTube.
+
+
+This script was made with ChatGPT 3 and fixed by hand.
+
+Prompt: "I have a lot of files named "file [youtube video ID].mkv". Make a bash script that recursively get those youtube videos ID and check if those videos are still available on youtube. If they aren't, output the ID to a text file."
+
+
+# Usage
+
+Copy this script next to the download script and run it.
+
+The list of available videos will be outputed to `unavailable_videos.txt` next to the script.
+
+
+# Warning
+
+This script is highly experimental and hasn't been as extensively tested as the other scripts.
+
+Nothing bad should happen, however, use it at your own risk.
+
+If you do run it and notice any bug with it, please open an issue.
