+===============================================================================
+YUJA-DL
+===============================================================================
+
+Download videos and subtitles from *.yuja.com with this script.
+Useful if your web-browser doesn't support streaming, or your PC is too weak
+to run one in the first place. Also useful for archival.
+
+I have a blog post on this over at https://xwx.moe/lib/ripping_hls_from_yuja.md
+
+----------------------------------------
+PRE-REQUISITES
+----------------------------------------
+You'll need:
+	* curl
+	* jq
+	* ffmpeg
+	* a shell 
+
+
+----------------------------------------
+USAGE
+----------------------------------------
+$ yuja-dl $VIDEO_URL $OUTPUT_NAME
+
+$VIDEO_URL should be in the format of "https://*.yuja.com/V/Video=?v=*".
+$OUTPUT_NAME will be the basename of the mp4 and srt files.
