+Canvas API for Deno, ported from [canvaskit-wasm (Skia)](https://github.com/google/skia/tree/master/modules/canvaskit). 
+
+## Installation
+Just import from raw GitHub URL, https://raw.githubusercontent.com/DjDeveloperr/deno-canvas/master/mod.ts. I'll publish on deno.land soon.
+
+## Usage
+mod.ts provides a default export exposing the complete CanvasKit API, and other exports from the file are types and util functions.
+
+```ts
+import Canvas, { CanvasRenderingContext2D } from '../mod.ts'
+import { serve } from "https://deno.land/[email protected]/http/server.ts";
+import { dataURLtoFile } from "../utils.ts";
+
+const canvas = Canvas.MakeCanvas(200, 200);
+const ctx = canvas.getContext('2d') as CanvasRenderingContext2D;
+
+ctx.fillStyle = 'red';
+ctx.fillRect(10, 10, 200 - 20, 200 - 20);
+
+const data = dataURLtoFile(canvas.toDataURL());
+
+const server = serve({ hostname: "0.0.0.0", port: 8080 });
+console.log(`HTTP webserver running. Access it at: http://localhost:8080/`);
+
+for await (const request of server) {
+  request.respond({ status: 200, body: data });
+}
+```
+
+And run with `deno run --allow-red --allow-read filename.ts`!
+Or you can directly run from URL, `https://raw.githubusercontent.com/DjDeveloperr/deno-canvas/master/examples/square.ts`
