+Introduction
+============
+
+Material Maker is a procedural material editor based on the Godot Engine.
+
+It can be used to describe the textures that define a material by interconnecting basic
+nodes that generate, transform or combine seamless textures in a graph.
+
+* Generator nodes describe configurable patterns that can be used to create the basic shapes
+  and textures of the material.
+
+* Transform nodes change the colors and shapes of their input images to create a more complex
+  texture.
+
+* Combine nodes use several input images to generate a new one.
+
+Many nodes in Material Maker are resolution independant, which makes it possible to use transforms
+to zoom on an image detail without affecting the generated texture quality. Only a few nodes such
+as the image generator and convolution filters (blur, emboss, normal map generation) will limit
+the resolution of their output.

+Blend node
+~~~~~~~~~~
+
+The blend node blends two inputs using an optional opacity. It performs a blend operation
+defined by the blend mode between both inputs, and mixes the result with the bottom input
+using the opacity (defines by the *opacity* parameter, or the optional greyscale input).
+
+.. image:: images/node_blend.png
+
+Inputs
+++++++
+
+The blend node accepts three inputs:
+
+* The first input is the top layer.
+
+* The second input is the bottom layer.
+
+* The third input is an optional mask that will be use instead of the opacity parameter.
+
+Outputs
++++++++
+
+The blend node outputs the result of the blend operation.
+
+Parameters
+++++++++++
+
+The blend node has two parameters:
+
+* The blend mode, that can be one of the following: Normal, Dissolve, Multiply, Screen,
+  Overlay, Hard Light, Soft Light, Burn, Dodge, Lighten, Darken, Difference.
+
+* The opacity used when mixing the result of the blend operation with the bottom input
+  when the corresponding input is not connected.
+
+Notes
++++++
+
+The *opacity* input will be considered (and implicitly converted to) greyscale if it is a color texture.

+.. image:: images/node_bricks.png
+
+Inputs
+++++++
+
+The bricks node does not accept any input.
+
+Outputs
++++++++
+
+The bricks node provides the following textures:
+
+* The first one is a greyscale image where bricks are shown in white and mortar in black.
+
+* The second one is a color image where all bricks are drawn using a random uniform color.
+
+Both images can be used together to create complex materials that show for example bricks
+of different colors.
+
+.. image:: images/bricks.png
+
+Parameters
+++++++++++
+
+The Bricks node accepts the following parameters:
+
+* the "Pattern" parameter defines the bricks pattern that will be generated.
+
+* the "Repeat" parameter defines the number of patterns on the horizontal and vertical
+  axes of the texture.
+
+* the "Rows" parameter defines the number of brick rows in a single pattern of the texture.
+
+* the "Columns" parameter defines the number of brick rows in a single pattern of the texture.
+
+* the "Offset" parameter defines the offset of odd rows of the pattern. This parameter
+  only applies to the "Running bond" patterns.
+
+* the "Mortar" parameter defines the relative thickness of mortar in patterns.
+
+* the "Bevel" parameter defines the relative thickness of brick bevel in patterns.
+
+Notes
++++++
+
+As with all random nodes, the seed is held by the node's position, so moving the node in the graph
+will modify the texture, and the outputs will remain the same if its position and parameters
+are not changed.

+User interface
+==============
+
+Overview
+--------
+
+Material Maker mainly consists of 3 panes:
+
+* The top left pane is the library, that contains all available nodes that can be used
+  to create materials. Library items are shown in a tree view
+
+* The bottom left pane is the preview, that shows at the same time the currecnt material
+  applied to a sample mesh in a sample environment, and the texture generated by the
+  currently selected node
+
+* The right pane contains the graph editors where materials are described for current
+  projects
+
+First steps with the user interface
+-----------------------------------
+
+When opening Material Maker, a new empty project is created and shown in the right pane.
+An empty project simply consists of a material node where textures for all elements of
+the material should be connected.
+
+To create a new node, simply choose one (for example "bricks") from the library (the
+top left pane) and drag it into the graph editor. Depending on the selected library
+item, a preview or a simple description will be displayed while dragging.
+
+.. image:: images/create_node.gif
+
+Selecting this new node (by clicking on it) shows it in the preview pane. The very small
+2d preview of the preview pane can be maximized by double cliking on it. This will hide
+the 3d preview but is useful when working on the different textures of the material.
+
+To connect a node output to an input of another node, simply drag one to the other.
+For example we can drag the first output of the Bricks node to the albedo input of
+the Materials node. This will automatically assign the simple Bricks texture to the
+albedo element of the material, and the 3d preview will immediately be updated (if
+you maximized the 2d preview it can be minimized by double-clicking on it again).
+
+.. image:: images/connect_nodes.gif
+
+Nodes can easily be configured by modifying their parameters, and previews are updated
+automatically.
+
+Since each input can be connected to a single output, reconnecting an input will
+automatically remove the previous connection.
+
+Main menu
+---------
+
+The main menu is organized in 4 sections:
+
+* the *File* menu contains actions to create, load, save and export materials
+* the *Edit* menu has common edit actions cut, copy and paste
+* the *Tools* menu has actions to add items to the user library
+* the *Help* menu can be used to find more information and submit feedback about the software
+
+File menu
+^^^^^^^^^
+
+* *New material* creates a new material and opens a tab in the right pane to edit it
+
+* *Load material* opens a file dialog to select a procedural material (.ptex) file. If
+  a material file is selected, it will be open in a new tab in the right pane. If the current
+  tab contains an empty material (about material that only consists of a Material node), the
+  material will be loaded into this tab.
+ 
+* *Save material* saves the current material. If it was not previously saved, a file dialog
+  will be displayed to select a location and file name.
+
+* *Save material as* prompts for a location and file name and saves the current material.
+
+* *Save all materials* saves all currently open materials. Materials that were not already
+  saved ae ignored.
+
+* *Export material* generates PNG image files for all elements of the material. File names are
+  defined using the path of the material and their role (albedo, metallic...) in the material.
+
+* *Close material* closes the current material.
+
+* *Quit* closes the software.
+
+Edit menu
+^^^^^^^^^
+
+* *Cut* Copies the selected nodes to the clipboard and removes them from the current material.
+
+* *Copy* Copies the selected nodes to the clipboard
+
+* *Paste* Copies the clipboard into the current material. Note that the nodes will be added to
+  the center of the view, so it is advised to scroll to the correct location before pasting.
+  Pasting also unselects all previously selected nodes and selects all newly created nodes,
+  so they can easily be moved around.
+
+Tools menu
+^^^^^^^^^^
+
+* *Add selected node to user library* first prompts for an item name. If a name is entered and
+  confirmed, the selected nodes in the current material will be added to the user library under
+  that name. Don't forget to use the *Save user library* item, otherwise the newly created library
+  not be available anymore when the software is restarted.
+
+* *Save user library* saves the user library.
+
+Help menu
+^^^^^^^^^
+
+* *Report a bug* opens a web browser on the Issues page of Material Maker's GitHub project. Please
+  do not hesitate to use it to suggest improvements for Material Maker.
+
+* *About* Shows the about dialog.
