+# DTA Data File Codec
+
+Codec for reading Stata .DTA files and generating CSF workbook objects
+compatible with the [SheetJS](https://sheetjs.com) library constellation.
+
+DTA datasets can support millions of observations and over 32767 variables.
+The codec will truncate data to 1048576 observations and 16384 variables.
+
+<https://docs.sheetjs.com/docs/constellation/dta> includes a live demo.
+
+## Installation
+
+Using NodeJS package manager:
+
+```bash
+npm install --save https://cdn.sheetjs.com/dta-0.0.2/dta-0.0.2.tgz
+```
+
+The standalone script is also hosted on the SheetJS CDN:
+
+```html
+<script src="https://cdn.sheetjs.com/dta-0.0.2/package/dist/dta.min.js"></script>
+```
+
+## Usage
+
+The `parse` method accepts a `Uint8Array` representing the file data. It returns
+a ["Common Spreadsheet Format"](https://docs.sheetjs.com/docs/csf/) workbook
+object.
+
+The `set_utils` method accepts a `utils` object from SheetJS CE or a SheetJS
+Pro build. `parse` will use methods from the `utils` object.
+
+### NodeJS
+
+```js
+const XLSX = require("xlsx"), DTA = require("dta");
+DTA.set_utils(XLSX.utils);
+
+const wb = DTA.parse(fs.readFileSync("auto.dta"));
+```
+
+### Browser
+
+`dist/dta.min.js` is a standalone build designed to be added with `<script>`.
+
+```html
+<script lang="javascript" src="https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js"></script>
+<script src="dist/dta.min.js"></script>
+<div id="out"></div>
+<script>
+DTA.set_utils(XLSX.utils);
+(async() => {
+  /* fetch file */
+  const data = await (await fetch("test.dta")).arrayBuffer();
+  /* parse */
+  const wb = DTA.parse(new Uint8Array(data));
+  /* wb is a SheetJS workbook object */
+  const html = XLSX.utils.sheet_to_html(wb.Sheets[wb.SheetNames[0]]);
+  out.innerHTML = html;
+})();
+</script>
+```
+
+`dist/dta.mjs` is a ECMAScript Module build designed to be used with bundlers:
+
+```js
+import * as DTA from 'dta';
+```
