GRASS begginer

Dear GRASS users,

Dear GRASS users,

I am just beginning with GRASS and having retrieved all the tutorials
I've found I still cannot display a raster image.
I've got a few ERDAS images (say 100 rows and 100 columns) and want to
setup a LOCATION and a MAPSET to be able to see them using d.display.
Incidentally, I do not know understand very well these two concepts.
What I need to know is the list of steps required to be able to see
an image .

Thank you in advance,
Julio C.Jacobo (jj20@zorzal.dc.uba.edu.ar)
