 ## Requirements
 - bash
-- awscli
-- gnu parallel
-- miller
-- python 3.13+
+- python 3.13+ with boto3 and openpyxl
 
 ## Usage
-Run run-inventory-scripts.sh which will invoke a collection of scripts. TSV is returned for visibility.
-Individual script can be ran to produce inventory of specific service. CSV is returned for programatic use.
+Run run-inventory-scripts.sh which will invoke a collection of scripts. Output will be written to aws-inventory.xlsx
