-There are 3 files that will be of interest. `schema.py` defines the Pandera schema used for validating the SBLAR data. A custom Pandera Check class called `NamedCheck` exists within this file as well. `check_functions.py` contains a collection of functions to be run against the data that are a bit too complex to be implemented directly within the schema as Lamba functions. Lastly, the file `main.py` pulls everything together and illustrates how the schema can catch the various validation errors present in our mock, invalid dataset.
+There are few files in `src/validator` that will be of interest. 
+- `checks.py` defines custom Pandera Check class called `SBLCheck`. 
+- `global_data.py` defines functions to parse NAICS and GEOIDs.
+- `phase_validations.py` defines phase 1 and phase 2 Pandera schema/checks used for validating the SBLAR data.
+- `check_functions.py` contains a collection of functions to be run against the data that are a bit too complex to be implemented directly within the schema as Lambda functions.
+- Lastly, the file `main.py` pulls everything together and illustrates how the schema can catch the various validation errors present in our mock, invalid dataset and different LEI values.
 
 ## Test data

-The repo includes 2 test datasets, one with all valid data, and one where each line
+- The repo includes tests that can be executed using `pytest`.  These tests can be located under `src/tests`.
+- The repo also includes 2 test datasets for manual testing, one with all valid data, and one where each line
 represents a different failed validation, or different permutation of of the same
 failed validation.

 ```sh
 # Test validating the "good" file
 # If passing lei value, pass lei as first arg and csv_path as second arg
+python src/validator/main.py 000TESTFIUIDDONOTUSE SBL_Validations_SampleData_GoodFile_03312023.csv
 # else just pass the csv_path as arg
