 Tired of inconsistent environment variable handling 😮‍💨? Tired of having to use `os.LookupEnv` and implementing parsing every time you need to extract a value 😩? Are you especially tired of seeing duplicate code blocks when variables are used in more than one place 😤? Enter standardized environment variable parsing!
 
 A stepwise instruction for a better way of life:
+
 1. Define a place where you want your environment variables to be declared. This could be your application's main entrypoint, or a separate `env` package, whatever your heart desires.
 2. Register your environment variables in the chosen place. Determine which are required and their datatypes.
 3. Call `Parse()` and your declared variables are good to go.
