Starting today, ARC's documentation is being migrated to a new site. The links in the menus above have been updated to reflect the move. Longer-term, the rest of ARC's website will be redesigned and simplified to provide higher-level information about ARC's mission and services.
The documentation is now based around ReadTheDocs and Sphinx, tools designed specifically for documentation. Leveraging these tools should make it more tractable to keep our documentation updated and complete.
