+# CUE-sheet generator for youtube-dl
+
+# Usage:
+# 0. Install 'jq' utility
+# 1. Download any audio file with metadata from YouTube or Youtube Music, e.g.
+#    $ youtube-dl \
+#          --extract-audio \
+#          --audio-format flac \
+#          --audio-quality 0 \
+#          --format bestaudio \
+#          --write-info-json \
+#          --output "/tmp/ytm/%(playlist_title)s/%(channel)s - %(title)s.%(ext)s" \
+#          https://www.youtube.com/watch?v=lVpDQnXz34M
+#
+#    If audio file is already downloaded earlier then just fetch only its metadata:
+#    $ youtube-dl \
+#          --write-info-json \
+#          --skip-download \
+#          --output "/tmp/ytm/%(playlist_title)s/%(channel)s - %(title)s.%(ext)s" \
+#          https://www.youtube.com/watch?v=lVpDQnXz34M
+#
+# 2. Audio and metadata files MUST be named exactly similar (except extenstion),
+#    but it is not necessary to keep original names. Also they MUST be placed in
+#    the same directory. Example:
+#    /tmp/ytm/ABGT496.flac
+#    /tmp/ytm/ABGT496.info.json
+#
+# 3. To create CUE file run ytdlcue with a path to audio file:
+#    $ ytdlcue.sh /tmp/ytm/ABGT496.flac
+#
+#    A new file will be created in the same directory:
+#    /tmp/ytm/ABGT496.cue
