-### Templates
+# Templates
 
 This library supports the use of templates to easily send formatted messages to different providers. Sample templates can be found in `test/templates` within the subdirectories `cool-multi-lingual`, `generic-template-foo`, and `multiple-types-bar`.
 
 By default, `Config` will look for templates at `./templates`. However, this path can be manually adjusted if needed. 
 
-#### Language Localization
+# Language Localization
 
 With templates, users can easily send messages in different languages. A sample architecture for language localized templates can be found in the `cool-multi-lingual` directory within `test/templates`. This directory contains folders for English and Spanish language codes, 'en' and 'es' respectively. Each of these directories contains SMS, SMTP, and Webhook templates in the appropriate language. To send notifications in a specific language, users can simply provide the appropriate `languageCode` parameter to the `send()` function.
 
-#### Template Overrides
+# Template Overrides
 
 When looking at the sample templates, we can see that some of them support word substitution. For example, the generic SMTP template looks like this:
