 ## BUGS
+
 Bugs and suggestions should be reported at: <https://github.com/phihag/youtube-dl/issues>
+
+Please include:
+
+* Your exact command line, like `youtube-dl -t "http://www.youtube.com/watch?v=uHlDtZ6Oc3s&feature=channel_video_title"`. A common mistake is not to escape the `&`. Putting URLs in quotes should solve this problem.
+* The output of `youtube-dl --version`
+* The output of `python --version`
+* The name and version of your Operating System ("Ubuntu 11.04 x64" or "Windows 7 x64" is usually enough).
