 `p5.asciify` is a [`p5.js`](https://github.com/processing/p5.js) addon library for converting the main [`WebGL`](https://p5js.org/reference/p5/WEBGL/) drawing canvas into a grid of ASCII characters. 
 
+To use `p5.asciify` with a [`p5.js`](https://github.com/processing/p5.js) sketch in [`WEBGL`](https://p5js.org/reference/p5/WEBGL/) mode, ensure to include [`p5.js`](https://github.com/processing/p5.js) version [`v1.7.0`](https://github.com/processing/p5.js/releases/tag/v1.7.0) or later in your project, as it relies on the [`createFramebuffer()`](https://p5js.org/reference/#/p5/createFramebuffer) function.
