+
+## Installation 🔧
+  1. Start by putting the latest Bootstrap on your site.
+
+  2. Then add my script to the site. It should come at the end of the body, behind the Bootstrap script.<br>
+  
+  ```html
+<script src="https://cdn.jsdelivr.net/gh/danielsebesta/bootstrap-theme-switch@main/theme-switch.min.js" integrity="sha384-eHEyolGs5+4+fpMEEcNsT22uT/gvfdbYi7ILP66pDf3JIDHcinTASicxy7BS9RFC" crossorigin="anonymous"></script>
+``` 
+
+3. Now put this button somewhere in your code to make it work.
+```html
+<button id="theme-toggler" class="btn btn-secondary">🌞</button>
+```
+
+4. You're done! Now enjoy a simple dark theme switch.
+

+I created this script because I was very confused by the Bootstrap docs and wanted to make something very simple and functional for others right out of the box. There is also a version written directly by the Bootstrap team, which you can find in the source code of their Example pages.
