== Merging ANGLE from Upstream ==

When pulling in a new revision of ANGLE, you must run the script [https://trac.webkit.org/browser/webkit/trunk/Source/ThirdParty/ANGLE/update-angle.sh Source/ThirdParty/ANGLE/update-angle.sh] and follow its instructions. This script will attempt to update to a new version of ANGLE without losing WebKit changes.

== Fixing ANGLE Bugs ==

When fixing bugs in ANGLE, please create a new bug on [https://bugs.chromium.org/p/angleproject/issues/list Monorail] (Google's bug tracker) and attach the patch applied to WebKit so that changes can eventually be merged upstream instead of maintained locally. Be sure to update [https://trac.webkit.org/browser/webkit/trunk/Source/ThirdParty/ANGLE/changes.diff changes.diff] when committing downstream changes.
