-A mac specific commandline wrapper around youtube-dl and ffmpeg.
+A mac specific command-line wrapper for [youtube-dl](https://rg3.github.io/youtube-dl/) and [ffmpeg](https://ffmpeg.org/).  This application uses homebrew to install the youtube-dl and ffmpeg binaries to your mac.  If you don't have this software installed it will prompt you to install the software and automate it.  Of course you could download youtube-dl your self and just use that tool alone, but using this wrapper will speed up downloads as it will download videos or mp3s from youtube in parallel.
+
+Oh this will automatically create a folder on your desktop called YouTubeFiles.
+
+**Usage:**  
+**Full guide sorry for the details if this is redundant to you
+
+I suggest building a binary.  In order to do so, navigate to the folder with terminal.  Once inside run the command:
+
+    go build downloader.go
+
+
+This will create the binary that can be used from terminal via the command `./downloader`
+
+**Commands:**
+To download one song
+
+    ./downloader -music https://www.youtube.com/watch?v=OcIDeP8_Fto
+
+
+To download many songs just continue to add urls with the -music command in front
+
+    ./downloader -music https://www.youtube.com/watch?v=OcIDeP8_Fto -music https://www.youtube.com/watch?v=hpFZWeQq_EU
+
+**Same as the music download commands :-)**
+
+To download one video
+
+    ./downloader -video https://www.youtube.com/watch?v=OcIDeP8_Fto
+
+
+To download many videos just continue to add urls with the -music command in front
+
+    ./downloader -video https://www.youtube.com/watch?v=OcIDeP8_Fto -video https://www.youtube.com/watch?v=hpFZWeQq_EU
+
+Now... that can get tedious so I've also programmed a way to submit urls from a newline delimitated file.  At the moment it only does music downloads.
+
+
+    ./downloader -path ~/Desktop/myfile.txt -file true
+
+
+Lastly you can save tons of time by creating a **public** playlist on youtube or finding a public playlist on  youtube and download all the songs or videos from that playlist at once.  Notice the url has the word playlist it in
+
+     ./downloader -music https://www.youtube.com/playlist?list=PL_5Qq5Bm7m2bDQAZjz-Io0zv1Yc__wt2o -playlist true
+
+or... for videos
+
+    ./downloader -video https://www.youtube.com/playlist?list=PL_5Qq5Bm7m2bDQAZjz-Io0zv1Yc__wt2o -playlist true
