+Overview
+--------
+
+This package implements a parser in JavaScript that parses the industry standard [ICU Message strings][ICU] — used for internationalization — into an AST. The produced AST can then be used by a compiler, like [`intl-messageformat`][intl-mf], to produce localized formatted strings for display to users.
+
+This parser is written in [PEG.js][], a parser generator for JavaScript. This parser's implementation was inspired by and derived from Alex Sexton's [messageformat.js][] project. The differences from Alex's implementation are:
+
+- This project is standalone.
+- It's authored as ES6 modules compiled to CommonJS and the Bundle format for the browser.
+- The produced AST is more descriptive and uses recursive structures.
+- The keywords used in the AST match the ICU Message "spec".

 Usage
 -----
 
-Given a message like this:
+### Loading in the Browser
+
+The `dist/` folder contains the version of this package for use in the browser, and it can be loaded and used like this:
+
+```html
+<script src="intl-messageformat-parser/dist/parser.min.js"></script>
+<script>
+    IntlMessageFormatParser.parse('...');
+</script>
+```
+
+### Loading in Node.js
+
+This package can also be `require()`-ed in Node.js:
 
 ```js
-var photosMsg = 'On {takenDate, date, short} {name} took {numPhotos, plural,' +
-    '=0 {no photos :(}' +
-    '=1 {one photo.}' +
-    'other {# photos!}}';
+var parser = require('intl-messageformat-parser');
+parser.parse('...');
+```
+
+### Example
+
+Given an ICU Message string like this:
+
+```
+On {takenDate, date, short} {name} took {numPhotos, plural,
+    =0 {no photos.}
+    =1 {one photo.}
+    other {# photos.}
+}
+```
 
+```js
+// Assume `msg` is the string above.
 parser.parse(msg);
 ```
