Hey Alex, thanks for the great work - I appreciate that you took the time to improve the API docs for the whole project and standardized the configs!

I have left a few comments, mostly minor ones, except one related to the imports and exports. See more details below - happy to discuss it further later if needed.

good catch

Good work with this PR, the new docs are looking nice.

I think we should include the BaseProvider class for Parameters (so that customers can extend it and build their own provider) and check that DynamoDBPersistenceLayer is included in the exports - but we'll do it in separate PRs.
