-Building from git
------------------
+Default branch renamed to `main`
+--------------------------------
 
-The GTK sources are hosted on [gitlab.gnome.org](http://gitlab.gnome.org). The main
-development branch is called `main`, and stable branches are named after their minor
-version, for example `gtk-4-10`.
+The default development branch of GTK has been renamed to `main`.
+To update your local checkout, use:
+```sh
+git checkout master
+git branch -m master main
+git fetch
+git branch --unset-upstream
+git branch -u origin/main
+git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
+```

 GSK render nodes can be serialized and deserialized using APIs such as `gsk_render_node_serialize()` and `gsk_render_node_deserialize()`. The intended use for this is development - primarily the development of GTK - by allowing things such as creating testsuites and benchmarks, exchanging nodes in bug reports. GTK includes the `gtk4-node-editor` application for creating such test files.
 
-The format is a text format that follows the [CSS syntax rules](https://drafts.csswg.org/css-syntax-3/). In particular, this means that every array of bytes will produce a render node when parsed, as there is a defined error recovery method. For more details on error handling, please refer to the documentation of the parsing APIs.

In particular, this means that every array of bytes will produce a render node when parsed, as there is a defined error recovery method. For more details on error handling, please refer to the documentation of the aprsing APIs.
 
 The grammar of a node text representation using [the CSS value definition syntax](https://drafts.csswg.org/css-values-3/#value-defs) looks like this:
 **document**: `<node>\*`
-**node**: container [ "name" ] { <document> } | `<node-type> [ "name" ] { <property>* }` | "name"
+**node**: container { <document> } | `<node-name> { <property>* }`
 **property**: `<property-name>: <node> | <value> ;`
 
-Each node has its own `<node-type>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.
+Each node has its own `<node-name>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.
 
 When serializing and the value of a property equals the default value, this value will not be serialized. Serialization aims to produce an output as small as possible.
 
 To embed newlines in strings, use \A. To break a long string into multiple lines, escape the newline with a \.
 
-# Names
-
-### Nodes
-
-Nodes can be given a name by adding a string after the `<node-type>` in their definition. That same node can then be used further down in the document by specifying just the name identifying the node.
-
-### Textures
-
-Just like nodes, textures can be referenced by name. When defining a named texture, the name has to be placed in front of the URL.

-Title: Coordinate systems
-Slug: gtk-coordinates
-
-## Coordinate systems in GTK
-
-All coordinate systems in GTK have the origin at the top left, with the X axis
-pointing right, and the Y axis pointing down. This matches the convention used
-in X11, Wayland and cairo, but differs from OpenGL and PostScript, where the origin
-is in the lower left, and the Y axis is pointing up.
-
-Every widget in a window has its own coordinate system that it uses to place its
-child widgets and to interpret events. Most of the time, this fact can be safely
-ignored. The section will explain the details for the few cases when it is important.
-
-## The box model
-
-When it comes to rendering, GTK follows the CSS box model as far as practical.
-
-<picture>
-  <source srcset="box-model-dark.png" media="(prefers-color-scheme: dark)">
-  <img alt="Box Model" src="box-model-light.png">
-</picture>
-
-The CSS stylesheet that is in use determines the sizes (and appearance) of the
-margin, border and padding areas for each widget. The size of the content area
-is determined by GTKs layout algorithm using each widgets [vfunc@Gtk.Widget.measure]
-and [vfunc@Gtk.Widget.size_allocate] vfuncs.
-
-You can learn more about the CSS box model by reading the
-[CSS specification](https://www.w3.org/TR/css-box-3/#box-model) or the
-Mozilla [documentation](https://developer.mozilla.org/en-US/docs/Learn/CSS/Building_blocks/The_box_model).
-
-To learn more about where GTK CSS differs from CSS on the web, see the
-[CSS overview](css-overview.html).
-
-## Widgets
-
-The content area in the CSS box model is the region that the widget considers its own.
-
-The origin of the widgets coordinate system is the top left corner of the content area,
-and its size is the widgets size. The size can be queried with [method@Gtk.Widget.get_width]
-and [method@Gtk.Widget.get_height]. GTK allows general 3D transformations to position
-widgets (although most of the time, the transformation will be a simple 2D translation).
-The transform to go from one widgets coordinate system to another one can be obtained
-with [method@Gtk.Widget.compute_transform].
-
-In addition to a size, widgets can optionally have a **_baseline_** to position text on.
-Containers such as [class@Gtk.Box] may position their children to match up their baselines.
-[method@Gtk.Widget.get_baseline] returns the y position of the baseline in widget coordinates.
-
-When widget APIs expect positions or areas, they need to be expressed in this coordinate
-system, typically called **_widget coordinates_**. GTK provides a number of APIs to translate
-between different widgets' coordinate systems, such as [method@Gtk.Widget.compute_point]
-or [method@Gtk.Widget.compute_bounds]. These methods can fail (either because the widgets
-don't share a common ancestor, or because of a singular transformation), and callers need
-to handle this eventuality.
-
-Another area that is occasionally relevant are the widgets **_bounds_**, which is the area
-that a widgets rendering is typically confined to (technically, widgets can draw outside
-of this area, unless clipping is enforced via the [property@Gtk.Widget:overflow] property).
-In CSS terms, the bounds of a widget correspond to the border area.
-
-During GTK's layout algorithm, a parent widget needs to measure each visible child and
-allocate them at least as much size as measured. These functions take care of respecting
-the CSS box model and widget properties such as align and margin. This happens in the
-parent's coordinate system.
-
-Note that the **_text direction_** of a widget does not influence its coordinate
-system, but simply determines whether text flows in the direction of increasing
-or decreasing X coordinates.
-
-## Events
-
-Event controllers and gestures report positions in the coordinate system of the widget
-they are attached to.
-
-If you are dealing with raw events in the form of [class@Gdk.Event] that have positions
-associated with them (e.g. the pointer position), such positions are expressed in
-**_surface coordinates_**, which have their origin at the top left corner of the
-[class@Gdk.Surface].
-
-To translate from surface to widget coordinates, you have to apply the offset from the
-top left corner of the surface to the top left corner of the topmost widget, which can
-be obtained with [method@Gtk.Native.get_surface_transform].
