-### Using it with TypeScript
+##### TypeScript
 Since this module does not provide TypeScript Type Definitions if you try to import it like `import dotenv from "dotenv-defaults"` TypeScript will return an error.
 
 Instead you should load it like this:
 ```typescript
 import "dotenv-defaults/config"
 ```
 
-### Using it as a CLI
+##### CLI
 You can also call this module directly when using the node executable.
 So, for example if you are running a custom script with node and you want to load your environment variables you can do the following `node -r dotenv-defaults/config your-script.js`. (_When using this method, please make sure that you have installed dotenv-defaults with npm or yarn in the same directory_)
