* Added headers emphasising Work on the framework vs Join the community
sections, to raise the visibility of the community section.
* Added callouts to three main code/docs/translations areas, linking to
respective start pages.
* Moved some Writing code specific content from the start page to the
Writing code index. This clarifies the start page and adds content to the
previously empty Writing code index.
