How do I import new dimensions?

Importing additional Dimensions is simple, go to Import/Export > Manual, and from the Import Type menu choose Dimension Detail Import (you may have renamed Dimension Detail).

Now click on the Download Template link, and fill out the template. The table on the page seen below will tell you the fields required. This is a CSV import file, so make sure that there are no formulas or links, all your data should be fixed, and also do not enter any data outside the headed columns show in the template.
