+By default, the `fly` command will look for `flightplan.js` or `flightplan.coffee`.
+
+If you do not install the Flightplan module locally to your project (i.e. to support non-javascript projects) then make sure the global `node_modules` is in your Node.js path. For example:
+
+```bash
+$ export NODE_PATH=/usr/local/lib/node_modules
+$ fly <destination>
