 What you need to build your own jQuery
 ---------------------------------------
-* Make sure that you have Java installed (if you want to build a minified version of jQuery).
-If not, go to this page and download "Java Runtime Environment (JRE) 5.0"

-* You now have two options for building jQuery, if you have access to common UNIX commands (like `make`, `mkdir`, `rm`, `cat`, and `echo`) then simply type `make` to build all the components.
+Build Options
+--------------
 
-* The other option is if you have Ant installed (or are on Windows and don't have access to make). You can download Ant from here: [http://ant.apache.org/bindownload.cgi](http://ant.apache.org/bindownload.cgi)
-If you do have Ant, everytime (in this README) that I say 'make', do 'ant' instead - it works identically (for all intents and purposes).
+You now have **three** options for building jQuery:
+
+* **`make`**: If you have access to common UNIX commands (like `make`, `mkdir`, `rm`, `cat`, and `echo`) then simply type `make` to build all the components.
+
+* **`rake`**: If you have Ruby Rake installed (on either Windows or UNIX/Linux), you can simply type `rake` to build all the components.
+
+* **`ant`**: If you have Ant installed (or are on Windows and don't have access to make). You can download Ant from here: [http://ant.apache.org/bindownload.cgi].
 
 How to build your own jQuery
 -----------------------------
 
+*Note: If you are using either `rake` or `ant`, substitute your chosen method in place of `make` in the examples below. They work identically for all intents and purposes. Quick reference is also available for `rake` by typing `rake -T` in the `jquery` directory.*
+
 In the main directory of the distribution (the one that this file is in), type
 the following to make all versions of jQuery:
 
-`make`
+    make
 
-Here are each of the individual items that are buildable from the Makefile.
+*Here are the individual items that are buildable from the Makefile:*
 
-`make init`
+    make init
 
 Pull in all the external dependencies (QUnit, Sizzle) for the project.
 
-`make jquery`
+    make jquery
 
 The standard, uncompressed, jQuery code.  
-Makes: ./dist/jquery.js
+Makes: `./dist/jquery.js`
 
-`make min`
+    make min
 
 A compressed version of jQuery (made the Closure Compiler).  
-Makes: ./dist/jquery.min.js
+Makes: `./dist/jquery.min.js`
 
-`make lint`
+    make lint
 
 Tests a build of jQuery against JSLint, looking for potential errors or bits of confusing code.
 
-`make selector`
+    make selector
 
 Builds the selector library for jQuery from Sizzle.  
-Makes: ./src/selector.js
+Makes: `./src/selector.js`
 
 Finally, you can remove all the built files using the command:
   
-`make clean`
+    make clean
+
+Building to a different directory
+----------------------------------
+
+If you want to build jQuery to a directory that is different from the default location, you can...
 
-Additionally, if you want to install jQuery to a location that is not this
-directory, you can specify the PREFIX directory, for example:
+**Make only:** Specify the PREFIX directory, for example:
   
-`make PREFIX=/home/john/test/`
+    make PREFIX=/home/john/test/ [command]
+    
+With this example, the output files would be contained in `/home/john/test/dist/`
+
+**Rake only:** Define the DIST_DIR directory, for example:
+
+    rake DIST_DIR=/home/john/test/ [command]
+    
+With this example, the output files would be contained in `/home/john/test/`
+
+*In both examples, `[command]` is optional.*
+
+**Ant only:** You cannot currently build to another directory when using Ant.
