\ No newline at end of file
+A Python-based distance calculator to help determine how far new apartment complexes are from the office.
+
+## Scripts
+
+* **gcoder.py** - Takes an address on the command line and returns its latitude and longitude.
+  May use one of four different geocoding engines.
+* **dcalc.py** - Takes an address on the command line and returns its latitude and longitude,
+  distance from the VMware Carbon Black Boulder office, and projected drive time to the
+  Boulder office.  Uses Google APIs.
+* **batch_distance.py** - Same as dcalc, but uses CSV files for input and output.
+
+## Configuration File
+
+All scripts make use of a configuration file, called `geoapi.ini` by default, that contains the
+API keys.  Copy the file `geoapi.ini.template` and add your API keys.  You can also specify a different
+configuration file with the `-C` or `--config` option to each script.
