-My workflow involves planning my tour using tools like ArcGIS or CalTopo. Then,
-I take the stats between each leg (distance, vertical gain/loss) of the tour
-and run them through Munter.py and thence record its output to my field
-notebook.
+The program supports both imperial and metric, and has four "travel
+modes" at this time: uphill, flat, downhill, bushwhacking. It also
+supports a simple fitness modifier: slow, average, fast.
+
+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.
+
+There is also a GUI mode available, based on WxPython, which can be used
+by simply invoking like so:
+
+`./munter.py -g`
+
+### Use as a library
+
+You can also use Munter.py programmatically from Python, like so:
+
+`import munter`
+`est = munter.time_calc(distance=3.2, elevation=2300, fitness='slow')`
+
+This will store a value like "3.64914" in the `est` variable.
