+This is an import of Skia. See skia/include/core/SkMilestone.h for the milestone number.
+
+Current upstream hash: 4655534302e6a3601c77eae70cc65b202609ab66 (milestone 79)
+
+How to update
+=============
+
+To update to a new version of Skia:
+
+- Clone Skia from upstream using the instructions here: https://skia.org/user/download
+  Usually: `git clone https://skia.googlesource.com/skia`
+- Checkout the wanted revision (`git checkout -b <hash>`). See below for the current
+  hash.
+- Copy the entire source tree from a Skia clone to mozilla-central/gfx/skia/skia
+  (make sure that . files are also copied as .gn is mandatory).
+- Download gn: cd gfx/skia/skia/bin && python fetch-gn && cd -
+  Note that these scripts might need Python 2.7. Please use a virtualenv if needed.
+- cd gfx/skia && ./generate_mozbuild.py
+
+Once that's done, use git status to view the files that have changed. Keep an eye on GrUserConfig.h
+and SkUserConfig.h as those probably don't want to be overwritten by upstream versions.
+
+This process will be made more automatic in the future.
+
+Debug
+=====
+
+In case of issues when updating, run the command manually.
+For example, if the following error occurs:
+`subprocess.CalledProcessError: Command 'cd skia && bin/gn gen out/linux --args='target_os="linux" ' > /dev/null && bin/gn desc out/linux :skia sources' returned non-zero exit status 1`
+Run:
+`cd skia && bin/gn gen out/linux --args='target_os="linux"'`
+and look at the errors.
