 ### Multiple emails in the same template
 Templates can contain multiple HTML files from which to build emails. For example, the dark template has `signature.html` and `signature-reply.html`, which is a simpler version.
-
 Each HTML file will be treated as an email template, except for `*.inc.html`. See below ⬇️
 
 
-### Partials (*.inc.html)
-If you indeed have multiple emails in the same templates, you can be sure some of the HTML repeats.
+### Using partials (*.inc.html)
+By naming files with `*.inc.html`, they become partials. Partials will not be treated as templates (ignored), but they can be included in any HTML template using a `@include` HTML comment.
 
-Luckily, partials can be used for common parts (i.e. headers, footers).
-
-Partials *will not* be treated as an email template, but ignored when built. They can however be included in other HTML files, like so:
 ```html
 <section>
 <!-- @include footer.inc.html -->
 </section
 ```
 
+Partials are useful if you have bits of HTML that repeat, like headers, footers, etc.

 ## Template structure (examples)
+There are no rules regarding how to structure templates, but it's a good idea to create directories for a template group. <br/>
 There are 2 examples of template structures, one for the `light` email template and one for the `dark` one.

-Files are included via [gulp-preprocess](https://www.npmjs.com/package/gulp-preprocess).
-
 There's one convention you have to keep in mind: `all files that you wish to include should follow the *.inc.html format`. The gulp task ignores `*.inc.html` files, but will try to process & create email templates from all `.html` files.
 
 You are of course encouraged to change the default structure for your use case.
