 (respectively `npm run watch:dev` to build continuously and monitor changes in
 source files). You can use `npm run build:prod` (`npm run watch:prod`) to do
 the same in production mode (with minification etc).

+## Tips
+
+### Running with multiple configs
+
+Let's say you are looking for a place in different places far apart (e.g. both
+a house in the country for the weekends and a place in a city for the week),
+you can use multiple configuration file (in this case, two configuration
+files) to define everything.
+
+Indeed, `serve` command for the web app only use a subset of the
+configuration, basically only the `data_directory`, `database` URI and so on.
+So, you are free to use any config file for `serve` command and still run
+`import` commands multiple times with different configuration files, for
+different housing queries.
+
+This is kind of a hack on the current system, but is working!
+
+*Note*: You can also use this tip if you are living in a city split across
+multiple postal codes and want to implement constraints such as "close to
+place X if postal code is Y".
