We are sorry about any inconvenience but we are doing one last major change to the docs!
We are removing “legacy” from links. Anywhere you see legacy in the link, just delete it and the link will then work.
For example: old link
http://docs.ghielectronics.com/hardware/legacy/gadgeteering.html
new link
http://docs.ghielectronics.com/hardware/gadgeteering.html
