 Driver to run an openEO back-end that combines the collections and compute power of a set of openEO back-ends.

+When planning to do development, it is recommended to install it in development mode (option `-e`) with the `dev` "extra":
 
     pip install -e .[dev]
 
-## Usage
+
+## Configuration
+
+The openEO-Aggregator specific configuration,
+is grouped by an `AggregatorBackendConfig` container object
+(subclass of `OpenEoBackendConfig` as defined in the `openeo-python-driver` framework project).
+The most important config value is `aggregator_backends`, which
+defines the backends to "aggregate".
+See [`src/openeo_aggregator/config/config.py`](src/openeo_aggregator/config/config.py)
+for more details and other available configuration options.
+
+Use the env var `OPENEO_BACKEND_CONFIG` to point to the desired config path.
+For example, using the example [dummy config](src/openeo_aggregator/config/examples/aggregator.dummy.py)
+from the repo:
+
+    export OPENEO_BACKEND_CONFIG=src/openeo_aggregator/config/examples/aggregator.dummy.py
+
+When no valid openEO-Aggregator is set that way, you typically get this error:
+
+    ConfigException: Expected AggregatorBackendConfig but got OpenEoBackendConfig
+
+
+## Running the webapp
+
+Note, as mentioned above: make sure you point to a valid configuration file
+before trying to run the web app.
