 ## Getting TemplateTemplate
 
@@ -24,9 +24,36 @@ You've got a couple options for adding TemplateTemplate to your project:
 
 ## Usage
 
+If you're comfortable attaching TemplateTemplate to the browser's `window` object, you may do the following:
+
+```html
+<script src="./dist/templatetemplate.js"></script>
+<script>
+  // Verify everything loaded properly...
+  console.log(window.TemplateTemplate)
+</script>
+```
+
+Or, you may use the JavaScript module (ESM) version:
+
+```html
+<script type="module">
+  import TemplateTemplate from './dist/templatetemplate.mjs';
+
+  // Verify everything loaded properly...
+  console.log(TemplateTemplate);
+</script>
+```
+
+> [!NOTE]\
+> Full-featured examples of both of the above approaches are available in the [`example`](https://github.com/jgarber623/TemplateTemplate/blob/main/example) folder.
+
+> [!NOTE]\
+> If you're using an asset-bundling system (there are _so many_), refer to its documentation to determine which version of TemplateTemplate you should use (ESM, CommonJS, etc.).

 TemplateTemplate takes two arguments: a reference to a `<template>` element and an object of `insertions` defining the content to insert into the `<template>`.
