First set of minimal docs for the new Markdown server, which will eventually replace https://sites.google.com/site/skiadocs/.

Design of the new Markdown server is documented here:

  https://github.com/google/skia-buildbot/blob/master/doc/README.md

  You can see the server up and running here: http://skiadocs.com:8000/

  This is *reed because it adds a new top level directory to the skia repo.

+Overview
+========
+Skia is an open source 2D graphics library which provides common APIs that work
+across a variety of hardware and software platforms.  It serves as the graphics
+engine for Google Chrome and Chrome OS, Android, Mozilla Firefox and Firefox
+OS, and many other products.
+
+Skia is sponsored and managed by Google, but is available for use by anyone
+under the BSD Free Software License.  While engineering of the core components
+is done by the Skia development team, we consider contributions from any
+source.
+
+Roadmap
+-------
+For a look at high level items we have on tap the next 6-12 months, view our
+roadmap [here](https://docs.google.com/a/skia.org/document/d/1cjB8QBB6orRtvpDn2MHAr95K8I0QvVgyJfUq5zGjf1M).
+Note it is a living document that changes based on the requirements of our users.

+Project Roles
+=============
+
+The Skia open source project includes individuals working in a variety of
+roles.  Anyone can view the code, use the Skia library, file bugs, and submit
+patches.  This page describes in detail the kinds of roles that interested
+parties can assume.
+
+For more information on ways to get involved in Skia development, see the
+[Contributing to Skia page](/dev/contrib/).

+How to download Skia
+====================
+
+Install gclient and git
+-----------------------
+
+Follow the instructions on
+http://www.chromium.org/developers/how-tos/install-depot-tools to download
+chromium's depot_tools (which includes gclient ).
+
+depot_tools will also install git on your system, if it wasn't installed
+already.
+
+
+
+Configure git
+-------------
+
+    $ git config --global user.name "Your Name"
+    $ git config --global user.email you@example.com
+
+Download your tree
+------------------
+
+    $ mkdir skia
+    $ cd skia
+    $ gclient config --name . --unmanaged https://skia.googlesource.com/skia.git
+    $ gclient sync
+    $ git checkout master
+
+At this point, you have everything you need to build and use Skia!  If
+you want to make changes, and possibly contribute them back to the Skia
+project, read on...
+
+Making changes
+--------------
+
+First create a branch for your changes:
+
+    $ git checkout --track origin/master -b my_feature master
+
+After making your changes, create a commit
+
+    $ git add [file1] [file2] ...
+    $ git commit
+
+If your branch gets out of date, you will need to update it:
+
+    $ git pull --rebase
+    $ gclient sync
+
+Uploading changes for review
+----------------------------
+
+    $ git cl upload
+
+You may have to enter a Google Account username and password to authenticate
+yourself to codereview.chromium.org. A free gmail account will do fine, or any
+other type of Google account.  It does not have to match the email address you
+configured using git config --global user.email above, but it can.
+
+The command output should include a URL (similar to
+https://codereview.chromium.org/111893004/ ) indicating where your changelist
+can be reviewed.
+
+Once your change has received an LGTM ("looks good to me"), you can check the
+"Commit" box on the codereview page and it will be committed on your behalf.
+
+Once your commit has gone in, you should delete the branch containing your
+change:
+
+    $ git checkout master
+    $ git branch -D my_feature

+User Documentation
+==================
+
+If you want to write code that uses the Skia library, this is the place for you.
+
+The Skia graphics library can be used for drawing Text, Geometries, and Images:
+
+  * 3x3 matrices w/ perspective
+  * antialiasing, transparency, filters
+  * shaders, xfermodes, maskfilters, patheffects
+  * subpixel text
+
+Device backends for Skia currently include:
+
+  * Raster
+  * OpenGL
+  * PDF
+  * XPS
+  * Picture (for recording and then playing back into another Canvas)

+Tips & FAQ
+==========
+
+Tips and Tricks
+---------------
+
+### Bitmap Subsetting
+
+Taking a subset of a bitmap is effectively free - no pixels are copied or
+memory is allocated. This allows Skia to offer an API that typically operates
+on entire bitmaps; clients who want to operate on a subset of a bitmap can use
+the following pattern, here being used to magnify a portion of an image with
+drawBitmapNine():
+
+    SkBitmap subset;
+    bitmap.extractSubset(&subset, rect);
+    canvas->drawBitmapNine(subset, ...);
+
+FAQ
+---
+
+### Does Skia support HW acceleration?
+
+
+There are two ways Skia can take advantage of HW.
+
+1. Subclass SkCanvas
+
+Since all drawing calls go through SkCanvas, those calls can be redirected to
+a different graphics API. SkGLCanvas has been written to direct its drawing
+calls to OpenGL. See src/gl/
+
+2. Custom bottleneck routines
+
+There are sets of bottleneck routines inside the blits of Skia that can be
+replace on a platform in order to take advantage of specific CPU features. One
+such example is the NEON SIMD instructions on ARM v7 devices. See src/opts/
+
+### Does Skia support Font hinting?
+
+Skia has a built-in font cache, but it does not know how to actual render font
+files like TrueType? into its cache. For that it relies on the platform to
+supply an instance of SkScalerContext?. This is Skia's abstract interface for
+communicating with a font scaler engine. In src/ports you can see support
+files for FreeType?, Mac OS X, and Windows GDI font engines. Other font
+engines can easily be supported in a like manner.
