4This directory contains sources of Open CASCADE Technology (OCCT), a software
5development platform providing services for 3D surface and solid modeling, CAD
6data exchange, and visualization. Most of OCCT functionality is available in
7the form of C++ libraries. OCCT can be best applied in development of software
8dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical
9simulation (CAE).

27Packaging
28---------
29
30You can receive certified version of OCCT code in different packages.
31
32- Snapshot of Git repository: contains C++ header and source files of OCCT,
33 documentation sources, build scripts, and CMake project files.
34
35- Complete source archive: contains all sources of OCCT, generated HTML and PDF
36 documentation, and ready-to-use projects for building on all officially
37 supported platforms.
38
39- Binary package (platform-specific): in addition to complete source archive,
40 it includes binaries of OCCT and third-party libraries built on one platform.
41 This package allows using OCCT immediately after installation.
42
43Certified versions of OCCT can be downloaded from http://www.opencascade.com
44
45You can also find OCCT pre-installed on your system, or install it from
46packages provided by a third party. Note that packaging and functionality
47of such versions can be different from certified releases. Please consult
48documentation accompanying your version for details.

50Documentation
51-------------
52
53Open file doc/html/index.html to browse HTML documentation.
54
55If HTML documentation is not available in your package, you can:
56
57- Generate it from sources.
58
59 You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system.
60 and accessible in your environment (check environment variable PATH).
61 Use batch file *gendoc.bat* on Windows or Bash script *gendoc* on Linux
62 or OS X to (re)generate documentation.
63
64- Read documentation in source plain text (MarkDown) format found in
65 subfolder *dox*
66
67See *dox/dev_guides/documentation/documentation.md* for details.
68
69Building
70--------
71
72In most cases you need to rebuild OCCT on your platform (OS, compiler) before
73using it in your project, to ensure binary compatibility.
74
75Consult the file *dox/dev_guides/building/building.md* for instructions on
76building OCCT from sources on supported platforms.
