 ### This is a version of veency that compiles on OSX
-* It also has a fix for broken images on OpenGLES apps.
-* Uses SimulateTouch
+* Adds a "Skip black screens" option to enable VNC to work with Camera, OpenGLES apps.
+* Uses SimulateTouch.
 
 ### To compile...
 * git clone https://github.com/DHowett/theos.git
 * git clone https://github.com/iolate/SimulateTouch.git
 * "unzip theos_includes.zip" into theos/include  (or you can grab the headers from various places, iphone-dev, etc.)
 * Edit Makefile.osx,  change the framework path to where you have Xcode installed.
-* make -f Makefile.osx
+* make -f Makefile.osx package
 
 ### To install...
-* Copy the "Veency.dylib" file to this folder on your mobile:  /Library/MobileSubstrate/DynamicLibraries/
-* Power the device off and back on.
+* Copy the .deb file to the device and run "dpkg -i veency....deb"
+* Power the device off and back on.  (Not powering off and only restarting springboard may leave behind stray veency servers)
