+# Assam Budget Parser
+
+This parser processes the xslx file provided by Assam Government and maps all the budget codes mentioned in the "Head of Description" to its respective description.
+
+To use the script run
+
+```python
+python scripts/generate_processed_data.py path/to/the/xlsx/file
+```
+
+The above script will generate a csv and a sqlite file that can be consumed.
+
+# Structure
+
+**Exploration** contains the ipython notebooks used to do trials done for processing of the data file shared.
+
+**scripts** contains the final code script that can be directly used to process the data file.
