- Link supported airframes to the Airframe reference rather than portfolio pages (they may look pretty, but nowhere near as useful for developers. Add portfolio link up top.
- Change the somewhat empty "Project Milestones" to "Project Roadmap" and link to the high level roadmap. I removed the only milestone about Lorenz creating the software. If we end up adding a more detailed milestone section that could go in. 
- Added clear guidelines for users vs developers.
