 # Build AWS Lambda Layer zip file for Python Dependancies
 
-Creates an AWS Lambda Layers **optimized** zip file using the [Lambda Layer directory structure](https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html#configuration-layers-path), ensures compiled libraries are compatible with Lambda environment, and optimized to reduce file size.
+Creates an AWS Lambda Layers zip file that is **optimized** for: [Lambda Layer directory structure](https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html#configuration-layers-path), compiled library compatibility, and minimal file size.
 
 This function was created to address these issues:
 
-- Many methods of creating Lambda zip files for Python functions don't work for Lambda Layers because Lambda Layers require specific library paths within the zip
-- Some dependancies required compiled components, which requires that the zip is created in an environment that matches the Lambda runtime environment
-- Minimize the zip size by removing unnecessary items
