 ## Quick Start
 
+### Sample Videos
+
+If you can't find a video clip to begin with, or if you want to see a before-after comparison, we have prepared some sample clips for you. The quick start guide down below will also be based on the name of the sample clips.

+### For Command Line Beginners
+
+If you're unfamiliar of directories in command lines, then here's a short section that might help you to get started.
+
+For example, if you downloaded the sample input video to `C:\Users\[YourUsername]\Downloads`, then the full path of your input video will be `C:\Users\[YourUsername]\Downloads\sample_input.mp4`, vice versa. The output path is also relative. If you want to export the output video to the current directory, just specify the output video name such as `output.mp4`. However, if you want to put the output video in a different directory, you should use relative or absolute path, such as `C:\Users\[YourUsername]\Desktop\output.mp4`.
+
+If you're tired typing everything in, you can also drag the video file directly into the command line window, and Windows will fill in the full path of the video for you.
