+# PXON
+
+> A JavaScript module for importing, creating, manipulating, and exporting PXON data.
+
+> [Full API Documentation →](https://thematthewhudson.com/pxon/)
+
+[![Build Status](https://travis-ci.org/matthewhudson/pxon.svg?branch=master)](https://travis-ci.org/matthewhudson/pxon)
+[![Coverage Status](https://coveralls.io/repos/github/matthewhudson/pxon/badge.svg?branch=master)](https://coveralls.io/github/matthewhudson/pxon?branch=master)
+[![NPM version](https://badge.fury.io/js/pxon.svg)](http://badge.fury.io/js/pxon)
+
+## Installation
+
+```sh
+npm install pxon
+```
+
+And then import it:
+
+```js
+// using es modules
+import PXON from "pxon";
+
+// common.js
+const PXON = require("pxon").default;
+
+// AMD
+// I've forgotten but it should work.
+```
+
+Or use script tags and globals.
+
+```html
+<script src="https://unpkg.com/pxon/umd/pxon.min.js"></script>
+```
+
+And then grab it off the global like so:
+
+```js
+const PXON = PXON.default;
+```
+
+## Example Usage
+
+```js
+const PXON = require("pxon").default;
+const pxon = new PXON();
+
+// Import PXON-formatted JSON.
+pxon.import({ ... });
+
+// Set some EXIF data.
+pxon.artist = "Matthew Hudson";
+pxon.software = "https://make8bitart.com/";
+
+// Set a single pixel's value.
+pxon.setPixel(x, y, color, size);
+
+// Iterate over an ES6 HashMap of all pixels.
+for (let [key, pixel] of pxon.pixels) {
+  console.log(`${key}, ${pixel}`);
+  // <- 0:0, { x: 0, y: 0, size: 1, color: 'rgba(0, 0, 0, 1)' }
+}
+
+// Returns a PXON-formatted object.
+console.log(pxon.export());
+```
