3 When using Nominatim through the library, it can be configured in exactly
4 the same way as when running as a service. You may instantiate the library
5 against the [project directory](../admin/Import.md#creating-the-project-directory)
6 of your Nominatim installation. It contains all files belonging to the
7 Nominatim instance. This may include an `.env` file with configuration options.
8 Setting configuration parameters via environment variables works as well.
9 Alternatively to using the operating system's environment, a set of
10 configuration parameters may also be passed to the Nomiantim API object.
12 Configuration options are resolved in the following order:
14 * from the OS environment (or the dictionary given in `environ`,
15 (see NominatimAPI.md#nominatim.api.core.NominatimAPI.__init__)
16 * from the .env file in the project directory of the installation
17 * from the default installation in the configuration directory
19 For more information on configuration via dotenv and a list of possible
20 configuration parameters, see the [Configuration page](../customize/Settings.md).
