+Building HandBrake for macOS
+==========================================
+
+## Be prepared 
+
+The first step is to get your development environment right.
+
+ * [Download and install the Xcode Developer Tools](http://developer.apple.com/mac/) (you will need to register with Apple, but it's free)
+
+ * Download, compile, and install a current version of yasm:
+
+Open up the Terminal. That's found in your /Applications/Utilities folder. 
+
+In the window that appears, type the following:
+
+	curl http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz> yasm-1.3.0.tar.gz
+	tar -xvf yasm-1.3.0.tar.gz
+	cd yasm-1.3.0/
+	./configure ; make
+
+
+When that finishes, you'll need to install yasm. Type the following:
+	
+	sudo make install
+
+*(You'll need to enter your system password at this point and hit return)*
+
+Once yasm is installed, clean up by typing:
+
+	cd ../
+	rm -rf yasm-1.2.0 yasm-1.2.0.tar.gz 
+
+
+*Leave that Terminal window open for the next step.*
+
+## Meet your maker 
+
+In the Terminal window, type:
+
+	git clone https://github.com/HandBrake/HandBrake.git  handbrake-git
+	cd handbrake-git/
+	./configure --launch --launch-jobs=0 ; open build/
+
+
+This will take awhile. When it's done, you'll see a window in front of you with your freshly-built copies of !HandBrake and HandBrakeCLI.
+
+## Reach enlightenment 
+
+This is just a simple quick-start guide. For the real meat and potatoes, [see the latest OS X build documentation](https://github.com/HandBrake/HandBrake/blob/master/doc/BUILD-Mac). Topics covered there include:
+
+ * Running configuration and build commands on subsequent compiles (hint, do it from the build/ directory, not the root)
+
+ * Cleaning build files
+ 
+ * Tweaking contrib libraries
