+Datatracker information
+_______________________
+
+Content
+=======
+
+The files in this directory are modified versions of bootstrap v3.3.4.  This is
+a cumbersome way to customize bootsrap, but as of the time of writing this
+(03 Apr 2015), there seems to be no provision for including modifications
+within the distributed build environment without either editing files in
+place, or copying and modifying parts of the build environment.
+
+Modifications done::
+
+	less/variables.less	# modified with our datatracker-specific changes
+
+Setup
+=====
+
+In order to set up things to build new static/css/bootstrap* files, do the
+following (copied from http://getbootstrap.com/getting-started/#grunt)
+
+Bootstrap uses Grunt for its build system, with convenient methods for working
+with the framework. It's how we compile our code, run tests, and more.
+
+Installing Grunt
+----------------
+
+To install Grunt, you must first download and install node.js (which includes
+npm). npm stands for node packaged modules and is a way to manage development
+dependencies through node.js.
+
+Then, from the command line: Install grunt-cli globally with ::
+
+   npm install -g grunt-cli.
+
+Navigate to the root /bootstrap/ directory, then run::
+
+   npm install
+
+npm will look at the package.json file and automatically install the necessary
+local dependencies listed there.
+
+When completed, you'll be able to run the various Grunt commands provided from
+the command line.
+
+Usage
+=====
+
+Available Grunt commands
+------------------------
+
+::
+
+   grunt dist			# (Just compile CSS and JavaScript)
+
+Regenerates the /dist/ directory with compiled and minified CSS and JavaScript
+files. As a Bootstrap user, this is normally the command you want.
+
+::
+
+   grunt watch			# (Watch)
+
+Watches the Less source files and automatically recompiles them to CSS
+whenever you save a change.
+
+::
+
+   grunt test (Run tests)
+
+Runs JSHint and runs the QUnit tests headlessly in PhantomJS.
+
+::
+
+   grunt docs			# (Build & test the docs assets)
+
+Builds and tests CSS, JavaScript, and other assets which are used when running
+the documentation locally via jekyll serve.
+
+::
+
+   grunt			# (Build absolutely everything and run tests)
+
+Compiles and minifies CSS and JavaScript, builds the documentation website,
+runs the HTML5 validator against the docs, regenerates the Customizer assets,
+and more. Requires Jekyll. Usually only necessary if you're hacking on
+Bootstrap itself.
