-# Methodology
+# Methodology
+
+   1. Read input datasets
+   2. Pre-process GTFS transit route data
+      1. Filter to only include bus and Tram, Streetcar, Light Rail transit modes
+      2. Join GTFS agency, route, trip, and shape data into a single dataset
+   3. Pre-process hotspot tabular data
+      1. Remove whitespace from transit routes column
+      2. Split comma separated values into a list of transit routes
+      3. Add transit agency ids that match GTFS data
+      4. Explode transit routes into individual rows (one row per transit route)
+      5. Manually correct transit route ids that do not match GTFS data
+   4. Merge GTFS transit route data with hotspot tabular data
