All documentation for HAL should be moved to the HAL GitBook living at http://hal.gitbooks.io/dev/content/. Currently documentation is spread accross different locations / formats:

1. GitHub repository: https://github.com/hal/webpage
   This repository was used to generate a static webpage / blog at http://hal.github.io/
2. GitHub Wiki: https://github.com/hal/docs/wiki
   The wiki contains information about the source code, roadmap and version history.
