+## How is this different from `python-edl`?
+
+There are two important differences between `import edl` and `import pycmx` 
+and motivated my development of this module.
+
+1. The `pycmx` parser doesn't take timecode or framerates into account, 
+   and strictly treats timecodes like opaque values. As far as `pycmx` is 
+   concerend, they're just strings. This was done because in my experience, 
+   the frame rate of an EDL is often difficult to precisely determine and 
+   often the frame rate of various sources is different from the frame rate 
+   of the target track.
+   
+   In any event, timecodes in an EDL are a kind of *address* and are not
+   exactly scalar, they're meant to point to a particular block of video or 
+   audio data on a medium and presuming that they refer to a real time, or 
+   duration, or are convertible, etc. isn't always safe.
+
+2. The `pycmx` parser reads event numbers and keeps track of which EDL rows
+   are meant to happen "at the same time," with two decks. This makes it 
+   easier to reconstruct transition A/B clips, and read clip names from
+   such events appropriately.
+ 
 ## Should I Use This?
 
-At this time, this is (at best) alpha software and the interface will be 
-changing often. It may be fun to experiment with but it is not suitable
-at this time for production code.
+At this time, this is (at best) beta software. I feel like the interface is 
+about where where I'd like it to be but more testing is required.
