 New Formulae
 ------------
-Relative to every other stupid packaging system ever, this is trivial. Just
-fork it at: http://github.com/mxcl/homebrew and create a new recipe. Then ask
-me to pull. Using git made all this so much easier.
-
-To make a new package use brew mk:
+Firstly generate the formula:
 
     brew mk http://foo.org/foobar-1.2.1.tar.bz2
-    
-This will either open TextMate or print the location of the generated stub.
 
-HomeBrew is not an Autarky so any dependencies outside of OS X that a package
+You now have /usr/local/Library/Formula/foobar.rb.
+Now it would be useful to amend the formula based on its configure options:
+
+    brew install foobar --help
+
+Now you know foobar's configure options.
+
+    brew install foobar --interactive
+    
+This opens an interactive bash shell at the extracted tarball. You can now 
+install to the recommended prefix or just read the README and type `exit'.
+
+Try to install it:
+
+    brew install foobar
+
+If it worked, fork http://github.com/mxcl/homebrew and ask me to pull. If it 
+didn't you may need to dig a little deeper.
+
+I'll try to optimise the package when I pull, but it would be nice if you did
+that for me ;)
+
+HomeBrew is not an autarky so any dependencies outside of OS X that a package
 may require may be installed separately. We have functions to help with that.
 
+Other useful commands when contributing
+---------------------------------------
+    brew edit # opens Textmate with all of Homebrew as a project
+    brew edit foobar # opens that formula for editing in Textmate
+    brew install foobar --debug # if the build fails, you can fix it
+    brew [something] --verbose # you get a proper ruby backtrace
+    brew install foobar --interactive # you are dumped at a shell with the extracted tarball as PWD

 Yes please! Fork and improve :)

+1. upgrades, yeah still need this
+2. install multiple versions of tools, which is very useful for eg. Qt
+3. formula revisions, to allow upgrades irrespective of the underlying package
