 ## Overview
 
-`SwiftDotenv` is a small and compact Swift package that allows you to load and save `.env` files at runtime and query for those values as well as system provided environemntal values via `ProcessInfo`. It's a single abstraction for dealing with environment variables at runtime as well as a handy mechanism keeping your secrets and private keys safe in a local configuration file that doesn't get committed to version control, rather than hardcoding secret strings into your app or framework.
