This is the tutorial about the new Sage git workflow given by R. Andrew Ohana (Univ. of Washington) during Sage Days 54. Sage Days 54 was a conference aimed at transitioning the Sage developers workflow from its current mercurial setup to using git as its verson control software. Sage (http://www.sagemath.org) is an open source computer algebra system that is becoming a popular alternative to proprietary mathematics software.
