+// Package dotenv is a go port of the ruby dotenv library (https://github.com/bkeepers/dotenv)
+//
+// Examples/readme can be found on the github page at https://github.com/joho/godotenv
+//
+// The TL;DR is that you make a .env file that looks something like
+//
+//	SOME_ENV_VAR=somevalue
+//
+// and then in your go code you can call
+//
+//	godotenv.Load()
+//
+// and all the env vars declared in .env will be available through os.Getenv("SOME_ENV_VAR")
