3. The Blender Institute houses the offices of the Blender Foundation – as
well as a production studio and render farm – in Amsterdam, the
Netherlands. Revenues from Blender’s e-shop and media publishing
enable Ton Roosendaal and a small staff to work full-time on Blender,
organize activities for SIGGRAPH or the Blender Conference, support
development, documentation and training projects, maintain and host
blender.org services, and pay for bookkeeping and administration
expenses.
Blender is a true community effort. Maintenance, new projects and
roadmaps are all defined via open channels

6. Blender is a free and open source 3D animation
suite. It supports the entirety of the 3D
pipeline— modelling, rigging, animation,
simulation, rendering, compositing and motion
tracking, even video editing and game creation.
Advanced users employ Blender’s API for Python
scripting to customize the application and write
specialized tools; often these are included in
Blender’s future releases. Blender is well suited
to individuals and small studios who benefit from
its unified pipeline and responsive development
process. Examples from many Blender-based
projects are available in the showcase.

7. Blender is cross-platform and runs equally well on
Linux, Windows and Macintosh computers. Its
interface uses OpenGL to provide a consistent
experience. To confirm specific compatibility, the list
of supported platforms indicates those regularly
tested by the development team.
As a community-driven project under the GNU
General Public License (GPL), the public is
empowered to make small and large changes to the
code base, which leads to new features, responsive
bug fixes, and better usability. Blender has no price
tag, but you can invest, participate, and help to
advance a powerful collaborative tool: Blender is
your own 3D software.

10. Blender’s official documentation wiki is hosted on the
Blender Wiki. If you’d like to help improve the
documentation, just register for an account.
There is a guide on the wiki that walks through the process
of editing and creating wiki pages. It’s highly recommended
that you subscribe to the bf-docboard mailing list when
making bigger changes, so that all of the contributors can
avoid repeating work and get feedback.
