+@section diffs Modeling with OCCT: Key differences
+
+Open CASCADE Technology (OCCT) is an object-oriented C++ framework designed for rapid production of sophisticated CAD/CAM/CAE applications.
+In other words, it provides endless possibilities for raw 2D and 3D modeling in C++ environment.
+Unlike end-user software, it is used by the application developers and therefore strongly differs from the most popular CAD/CAM/CAE software packages.
+OCCT provides building blocks enough for modeling, editing, visualization, and data interoperability of 2D and 3D objects.
+
+By using OCCT, users can create the objects of their desire (or edit already existing ones) using raw code commands.
+It is a more complicated process than using GUI-based software, but it provides much more flexibility than even script-based manipulations that are available within existing CAD/CAM/CAE applications.
+However, to fully grasp the possibilities of OCCT it is best for the user to have previous experience in C++ at least at a basic level.
+
+@section basics Understanding the principles
+
+If you don't have any programming skills, grasping the full magnitude of OCCT workflow is still an option.
+The documentation for OCCT contains several entry points for new users.
+It will not explain all OCCT classes but will help to comprehend the workflow and help start thinking in terms of Open CASCADE Technology.
+
+The most basic workflow is described in the @ref occt__tutorial "OCCT Tutorial" - this is an excellent starting point for new users.
+In this tutorial you will create a solid model step-by-step using different classes and methods.
+Each step of the tutorial contains code snippets and images.
+
+The basics involved in the modeling process are explained.
+When the basics of OCCT are clear, the next logical step is to check out @ref samples "sample applications" and examine those that suit your needs.
+For these, the best starting point is **OCCTOverview** located in /samples/qt subfolder of OCCT installation.
+
+This sample provides code examples for several actions as well as visualization of these code snippets output.
+The Overview interface is dynamically changing based on selected **Category** at the menu.
+Additional menu buttons will appear, providing users with subcategories and relevant commands to select one of the actions.
+The result will appear in the viewer window, the code will appear at the top right, and in several cases the output will be produced at the bottom right window.
+
+@figure{sample_overview_qt_viewers.png,"Comparison of 3D and 2D viewer windows",240} height=420px
+
+The 3D viewer window has a row of preset interface buttons to customize the visual output.
+
+Those buttons can be grouped into three types, left to right:
+
+- View controls: **Fit all** and **Isometric**, will center the view and reset the camera angles respectively;
+- Display mode customization: **HLR,** e.g. "Hidden line removal" (works only when shading is disabled) can be turned on and off;
+solid models may be displayed either in **Shading** or **Wireframe** modes. **Transparency** level may be set for models in shading mode;
+- The last four buttons in a row are beautifiers enabling Ray-tracing engine and configuring it's parameters.
+
+At the bottom left of the screen the orientation cube (trihedron) is located.
+The trihedron interactively shows the position of the camera in relation to the XYZ axis of the displayed data.
+The sides of the trihedron are labeled to help with orientation.
+Click on a side of the box to orient the camera view along the preferred axis.
+
+The 2D viewer window lacks most of these elements and only have **Fit all** button.
+
+The **Geometry** category of the Overview focuses on primitive objects like dots, lines (including vectors) or planes.
+These objects will appear in the viewer after the subcategory is selected.
+This section will demonstrate these entities both in 2D and 3D view mode and provide basic examples of parametric creation and data analysis.
+
+@figure{sample_overview_qt_geometry.png,"",240} height=440px
+
+The usage of the functions shown in the Overview is described more thoroughly at the @ref occt_user_guides__modeling_data "Modeling data" section of the documentation.
+Additionally, @ref occt_user_guides__modeling_algos "Modeling Algorithms" are used in more complex cases.
+
+The **Topology** section of the Overview demonstrates the functions used in 3D operations.
+Multiple use cases are provided, including different object intersections, modifying and calculations.
+Some of these use cases are described in the documentation, such as @ref occt_user_guides__inspector "Inspector" usage.
+
+@figure{sample_overview_qt_topology.png,"",240} height=440px
+
+The subsections are grouped as shown on the screenshot before.
+Most shapes and primitive objects are introduced and then followed by a set of operations and interactions.
+
+The **Triangulation** segment allows computing the number of triangles on a shape.
+
+This may be inspected via [Poly_Triangulation Class Reference](https://dev.opencascade.org/doc/refman/html/class_poly___triangulation.html) -
+a part of the [Reference manual](https://dev.opencascade.org/doc/refman/html/index.html),
+an overall Open CASCADE code guide that may be used to inspect the key points in classes and their connections.
+
+@figure{sample_overview_qt_triangulation.png,"",240} height=440px
+
+The triangulation uses some of Mesh-related classes - see full description at @ref occt_user_guides__mesh "Mesh" documentation section.
+
+The **Data exchange** section provides examples of how to export and import files of several different formats.
+
+@figure{sample_overview_qt_xde.png,"",240} height=440px
+
+The **OCAF** section gives an introduction for the @ref intro_overview_ocaf "Open CASCADE Application Framework" functionality.
+To test these functions, create an object first (box or cylinder).
+After that, the object may be modified and saved. Actions are recorded and may be undone or redone.
+
+@figure{sample_overview_qt_ocaf.png,"",240} height=440px
+
+**Viewers** section demonstrates examples of the 2D and 3D visualization outputs.
+Check @ref occt_user_guides__visualization "Visualization" section of the documentation for a detailed description.
+In addition to these two samples, there are much more that might be of use to a new user based on their particular use case.
+
+Check Readme files in the sample directories to learn more about samples compilation.
+
+**Note:** source code for OCCTOverview is stored at 'samples/qt/OCCTOverview/src' folder in your OCCT root,
+and the source code files for examples presented in subsections are stored at 'samples/OCCTOverview/code folder'.
+Several utility classes that are not presented in the example window may be found in example source code files.
+
+The overall classes introduction may be found in the @ref occt_user_guides__foundation_classes "Foundation Classes" section of the documentation.
+The "Introduction" section contains short descriptions of the most massive entries in the documentation.
+
+@section helps Additional assistance
+
+There are several places that may be of use for new users.
+The first one is [Training & E-learning](https://dev.opencascade.org/resources/trainings) page that lists available trainings and describes their specifics.
+
+The second one is the Overview documentation (this document is a part of it) - here you can find information that suits most of the use cases.
+This may seem overwhelming at first, but if you have the clear understanding of what do you seek, you will most likely find the required information.
+
+Aside from the Overview documentation itself, the [Reference manual](https://dev.opencascade.org/doc/refman/html/index.html) is present.
+Use it to check classes descriptions, dependencies and examples.
+Additionally, there is a [Forum](https://dev.opencascade.org/forums) where you can contact the OCCT community and developers.

+Qt: Bottle Tutorial (C++|Qt Widgets) {#samples_qt_tutorial}
+==========
+
+The Qt programming tutorial teaches how to use Open CASCADE Technology services to model a 3D object.
+The purpose of the tutorial is not to explain all OCCT classes but to help start thinking in terms of the Open CASCADE Technology.
+
+This tutorial assumes that  the user has experience in using and setting up C++.
+From the viewpoint of programming, Open CASCADE Technology is designed to enhance user's C++ tools with high performance modeling classes, methods and functions.
+The combination of these resources allows creating substantial applications.
