+== Features ==
+=== View widgets ===
+- Shows the output of a Gegl graph.
+- QML, QGraphicsView and QWidget versions are provided.
+- Scaling and translation is supported.

+
+== Purpose & Scope ==
+The purpose of gegl-qt is to make it easy for application developers to
+use GEGL in applications with Qt based user interfaces.
 
-== Scope ==
-gegl-qt aims to support Qt4 and both QWidget, QGraphicsView and QML.
+gegl-qt aims to support Qt4 and both QWidget, QGraphicsView and QML based user interfaces.
 Qt5 support will be considered in the future.
 
-The QML support provided by gegl-qt is meant to enable application writers
-to show Gegl graphs in their QML-based user interface. Providing QML bindings 
-for GEGL so that the graphs can be manipulated programatically using QML is 
-considered to be out-of-scope.
+It is currently outside the scope of gegl-qt to provide C++ (Qt/QObject) or QML bindings
+for GEGL. If you are interested in this, the best way would be to use GObject
+Introspection + Smoke GObject.
+
+== Contributing ==
+To contribute code, please file a bug and attach git-formatted patches there, or link to
+a public git branch which has the commits (on github for instance).
+For quick, simple and obvious fixes, you may send a patch to the mailinglist.
+
+For a list of tasks that needs to be done see the TODO section of this document,
+and the TODO, FIXME and XXX comments in the source code.
 
 == TODO ==
+Currently the focus is on the 0.1.0 release. The 0.1 series will
+have a basic set of features, and maintain ABI and API compatability.
+
+=== 0.1.0 ===
+First release. Goal: minimally useful, solid interfaces.
+Should at happen before or together with the next Gegl release.
+Need to build and work with whatever is the latest Gegl release.
+
+- Fix out-of-tree build
+- Use a namespace, GeglQt, instead of symbol prefix
+- Find good and consistent names for the different view widgets
+- Do API review
+- Create 'make dist' and 'make distcheck' targets
+- Have a basic set of tests, and good test infrastructure
+- Distribute a basic examples for the provided features
+- Add information about gegl-qt to gegl.org website
+
+- Display operation needs to spin its own mainloop
+- Register the display operation as a 'display' type operation (needs support in Gegl)
+
+=== Later ===
 General
-- Python support using PySide and Shiboken
+- Python support using PySide and Shiboken (see 'pyside' branch)
+- API documentation
 
 View widgets
-- Translation
-- Scaling
-- Rotation
+- Rotation support
+- Background and overlay draw support for GeglQtView
+
+QImage IO loader plugin that uses
+
+Tests
+- Unittests for view widgets
+- Regression tests for view widgets rendering
+- Performance benchmarks for view widgets
+
+Examples
+- Interactive examples of Gegl + GeglQt features
+
+=== Maybe ===
+Additional widgets?
+
+- Graph view: Show the entire Gegl graph and allow to manipulate it
+Add/remove and reorder operations.
+- Node properties view: show the properties of a given Gegl node in a graph,
+and allow to manipulate them.
