+# RequireJS
+
+RequireJS loads plain JavaScript files as well as more defined modules. It is
+optimized for in-browser use, including in
+[a Web Worker](http://requirejs.org/docs/api.html#webworker), but it can be used
+in other JavaScript environments, like Rhino and
+[Node](http://requirejs.org/docs/node.html). It implements the
+[Asynchronous Module](https://github.com/amdjs/amdjs-api/wiki/AMD)
+API.
+
+RequireJS uses plain script tags to load modules/files, so it should allow for
+easy debugging. It can be used
+[simply to load existing JavaScript files](http://requirejs.org/docs/api.html#jsfiles),
+so you can add it to your existing project without having to re-write your
+JavaScript files.
+
+RequireJS includes [an optimization tool](http://requirejs.org/docs/optimization.html)
+you can run as part of your packaging steps for deploying your code. The
+optimization tool can combine and minify your JavaScript files to allow for
+better performance.
+
+If the JavaScript file defines a JavaScript module via
+[define()](http://requirejs.org/docs/api.html#define), then there are other benefits
+RequireJS can offer: [improvements over traditional CommonJS modules](http://requirejs.org/docs/commonjs.html)
+and [loading multiple versions](http://requirejs.org/docs/api.html#multiversion)
+of a module in a page. RequireJS also has a plugin system that supports features like
+[i18n string bundles](http://requirejs.org/docs/api.html#i18n), and
+[text file dependencies](http://requirejs.org/docs/api.html#text).
+
+RequireJS does not have any dependencies on a JavaScript framework.
+
+RequireJS works in IE 6+, Firefox 2+, Safari 3.2+, Chrome 3+, and Opera 10+.

+
+## Directories
+
+* **dist**: Scripts and assets to generate the requirejs.org docs, and for
+generating a require.js release.
+* **docs**: The raw HTML files for the requirejs.org docs. Only includes the
+body of each page. Files in **dist** are used to generate a complete HTML page.
+* **tests**: Tests for require.js.
+* **testBaseUrl.js**: A file used in the tests inside **tests**. Purposely
+placed outside the tests directory for testing paths that go outside a baseUrl.
+* **updatesubs.sh**: Updates projects that depend on require.js Assumes the
+projects are siblings to this directory and have specific names. Useful to
+copy require.js to dependent projects easily while in development.
+
+## Tests
+
+This repo assumes some other repos are checked out as siblings to this repo:
+
+    git clone https://github.com/requirejs/text.git
+    git clone https://github.com/requirejs/i18n.git
+    git clone https://github.com/requirejs/domReady.git
+    git clone https://github.com/requirejs/requirejs.git
+
+So when the above clones are done, the directory structure should look like:
+
+* domReady
+* i18n
+* text
+* requirejs (this repo)
+
+You will need to be connected to the internet because the JSONP and
+remoteUrls tests access the internet to complete their tests.
+
+Serve the directory with these 4 siblings from a web server. It can be a local web server.
+
+Open requirejs/tests/index.html in all the browsers, click the arrow button to run all
+the tests.
