+The program supports both imperial and metric, and has four "travel
+modes" at this time: uphill, flat, downhill, bushwhacking.
+
+By default, the output will be the time in hours and minutes of the
+specified leg. If you prefer, you can use the `-p` switch to get a
+"prettier" output.
+
+### Use as a library
+
+You can also use Munter.py programmatically from Python, like so:
+
+`import munter`
+`est = munter.time_calc(3.2, 2300, 'uphill', 'imperial')`
+
+This will store a value like "3.04095" in the `est` variable.
