Git trivia

After checking out, run this to materialize subdirs://

git submodule update --init --recursive

Append --remote to upgrade to newest versions of all submodules (need to commit afterwards if anything changed).

@cben is directly working in the gh-pages branch without a master branch, as that’s the simplest thing that could possibly work (http://oli.jp/2011/github-pages-workflow lists several alternatives).

Note

About the redesign

The redesign was inspired by this discussion, and as an experiment in search for how wysiwyg Markdown editing could look like.
