Documentation has moved to marlinfirmware.org.
Our development effort has moved to a companion Github repository MarlinDev.
That repository is based on the same git tree as this one. To move to the new repository, Simply add the new one as an additional git remote to your existing infrastruction and begin fetching and syncing to that repository rather than this one.
As soon as we complete the transition and close the remaining items based on it, this branch will be deleted.
