 ## Data Pipeline
 
-The pipeline consists of two files, `gcc_puller_functions.py` for the functions and `gcc_layers_pull.py` for the Airflow DAG. The main function that fetches the layers is called `get_layer` and it takes in five parameters. Here is a list that describes what each parameter means:

 ## Adding new layers to GCC Puller DAG
 1. Identify the mapserver_n and layer_id for the layer you wish to add. You can find COT transportation layers here: https://insideto-gis.toronto.ca/arcgis/rest/services/cot_geospatial2/FeatureServer, where mapserver_n is 2 and the layer_id is in brackets after the layer name.
