 # Project Structure
 
-Two notebooks:
+*Dhaka data from US Embassy:* Two notebooks,
+1) Pre-processing: Imports and cleans the raw dataset and exports cleaned csv file.
+2) Analysis and Visualisation: Imports clean dataset and does the analysis of the data and creates the visuals.
+
+And a script to download the csv data files.

+*CASE nationwide data:* Two notebooks,
 1) Pre-processing: Imports and cleans the raw dataset and exports cleaned csv file.
 2) Analysis and Visualisation: Imports clean dataset and does the analysis of the data and creates the visuals.
