Clear and Smart Technical Writing, CaST Writing for short, is a modern workflow to draft technical documents based on different free software components such as Markdown and Atom.

• clear minimalistic interface
• clear writing tooltips
• document versioning (version control)
• track changes (differences between versions)
• merging of diverging versions
• concurrent editing (similar to Google Docs)
• offline support and multi-device support
• platform independent (for Windows, Mac and Linux)
• reference management (citations)

Text in structured Markdown syntax is written in the Atom editor and stored in simple plain-text Markdown files. These files are versioned using Git and converted to the desired output format using the tool Pandoc.
