 #### Public ARNs
 
-We build, release and distribute packaged Lambda Powertools layers for each region. This means you can copy a specific ARN and use it in your Lambda deployment. The layer region must be in the same region as your lambda function. The public layers do not contain the `pydantic` library that is required for the `parser` utility.
