 '''Installing a Build'''
-Right now I have the latest build stored [http://www.bassified.nl/firefox-3.7a1pre.en-US.win32.d2d.2009.12.3.zip on my server]. Until we have the DirectX SDK installed on the try servers. This is a build without PGO, with a simple --disable-debug --enable-release mozconfig. Its performance should not be compared to normal build server builds at this point.
+Mozilla 1.9.3 (mozilla-central) builds as of Friday, February 26, 2010, contain support for Direct2D and DirectWrite. This also includes Mozilla 1.9.3 alpha 2.
 '''Starting the build'''

 The best way to start is is to just run the firefox executable with a special d2d profile. (i.e. firefox -no-remote -P d2d) A second instance can then be ran in order to make comparisons on a different profile.
-'''Using GDI'''
+'''Using Direct2D'''
-To compare or demo the performance difference it's possible to use GDI in one of my builds. Create a separate profile for your GDI version. And for that profile set the 'font.engine.forcegdi' pref to true. Note that if you do this from about:config it will need a restart before it starts using GDI.
+By default, Direct2D and DirectWrite are turned off. Steps to turn it on:
+# Enter 'about:config'
+# Click through the warning, if necessary
+# Enter gfx.font in the 'Filter' box
+# Double-click on 'gfx.font_rendering.directwrite.enabled' to set it to true
+# Below this, right click and select New > Integer to add a pref setting
+# Enter 'mozilla.widget.render-mode' for the preference name, 6 for the value
+# Restart
