 ## Usage
+You can load it directly using a CDN as follows
+
+```html
+<script src="https://unpkg.com/telescopic-text/index.js"></script>
+<link href="https://unpkg.com/telescopic-text/index.css" rel="stylesheet">
+```
+
+or manually include the `index.js` and `index.css` files in your project.
+
+The package exports a function called `createTelescopicText` that returns a HTMLNode with your telescopic text inside.
+Basic usage may look something like this:
+
+```html
+<div id="text-container"></div>
+
+<script>
+    const node = createTelescopicText([
+        {text: "I made tea.", replacements: [
+            {og: "I", new: "Yawning, I", replacements: []}
+        ]}]
+    ])
+    const container = document.getElementById("text-container")
+    container.appendChild(node)
+</script>
+```
