 ## Automatic Linear Editor
 
 Give ALE a video and a target length, and ALE will automatically create a highlight reel for you.
+
+```
+usage: ALE [-h] [-p PARALLELISM] [--cost-function {quadratic}] [--min-duration MINDUR]
+           [--max-duration MAXDUR] [--intro-video INTROVIDPATH] [--outro-video OUTROVIDPATH]
+           [--title-slide-text OUTROVIDPATH] [--title-slide-duration OUTROVIDPATH]
+           file duration destination {amplitude,sentiment} ...

+ALE: Automatic Linear Editor.
+
+positional arguments:
+  file                  Path to the video file to edit
+  duration              Target length of the edit, in seconds
+  destination           Edited video save location
+  {amplitude,sentiment}
+                        The editing algorithm to use
+    amplitude           The amplitude editor uses audio amplitude moving averages to find swings
+                        from relatively quiet moments to loud moments. This is useful in videos
+                        where long moments of quiet are interspersed with loud action filled
+                        moments.
+    sentiment           The sentiment editor transcribes the speech in a video and runs sentiment
+                        analysis on the resulting text. Using moving averages, large swings in
+                        sentiment can be correlated to controversial or exciting moments. A GPU with
+                        CUDA is recommended for fast results.
+

+                        The number of cores to use, defaults to N - 2 cores.

+                        Text to show during a title slide. The title slide is played after any
