 Here is a tutorial of the current development features:
 
-	Do you have a help manual?
-		1) Yes, go to http://www.openshotusers.com/help/en/
-
-	How do I add media to my project?
-		1) Drag and drop videos or music files from gnome into the "Project Files" tree.
-		2) Click the File / Import Files... menu
-		3) Click the "Import Files" icon on the toolbar (at the top of the screen)
-		
-	How do I add media to my timeline?
-		1) Click on any file in your "Project Files" tree, and drag it onto the timeline (at the bottom of the screen)
-		
-	How do I position clips on my timeline?
-		1) Simply click on any clips already on the timeline, and drag them to their new location
-		2) Use the magnet icon to have your clips magically stick to their closest neighbor clips.
-		
-	How do I trim / un-trim clips
-		1) Click and drag the edge of the clip to it's new location.
-
-	The audio / video is out of sync. What can I do?
-		1) This is usually related to a bug in libopenshot or FFmpeg.  To resolve this, re-encode the video using the 
-		   ffmpeg command line tool.
-		   
-		2) Here is an example command to convert a folder full of Canon MTS files to MP4:
-		   $ find '/home/jonathan/Desktop/Caveman Movie/Videos' -iname "*.MTS" -exec ffmpeg -i {} -acodec libfaac -ab 128k -ac 2 -r 60 -vcodec mpeg4 -f mp4 -y -sameq {}.mp4 \;
-
-		3) Usually the reason the A/V are out of sync is related to the frame rate (i.e. the -r parameter on the ffmpeg command).
-		   Try a variety of frame rates and OpenShot project types to find one that doesn't have A/V sync issues.
-		   Some common rates are:  -r 29.97  -r 25  -r 30  -r 60
