+## Notes
+
+### Svelte 3
+
+Because of the code in Range Slider Pips 3, it is now incompatible with Svelte version 3. 
+
+If you are unable to upgrade your project, then I suggest looking for [Svelte-Range-Slider-Pips version `2.3.1`](https://github.com/simeydotme/svelte-range-slider-pips/tree/2.3.1) which
+will not be upgraded, but it's still pretty robust. You can install it like so;
+
+```bash
+yarn add [email protected] --dev          # or
+npm install [email protected] --save-dev  # if you prefer npm
+```
