Double click on a link (the line joining the end of one phase to the start of the next) to set any required lead / lag time. You can link dates freely - start to start, finish to start etc.
If you use a 2 tier structure of phases and stages, and your system is set to use stage-driven dates then you will see phases and stages in the Gantt view, with the ability to link stages together via dependencies. New items can be added by clicking the + icon in line with a Gantt bar.
