 You must use this dataset's format in all the gdal tools, like gdalinfo, gdal_translate, gdalwarp, etc.
 
+'''Example 1:'''
+
+To get info about ''utm.tif'' file stored in database (see section 3.1) run this command:
+
+{{{
+>$ gdalinfo -mm -stats -checksum "PG:host='localhost' dbname='<wktraster_database>' user='<wktraster_user>' password='<wktraster_password>' table='utm'"
+}}}
+
+As user / password, in a common installation, you can use '''postgres / postgres'''
+
+
+'''Example 2:'''
+
+To get an overview of the original image with half size (meaning image dimensions, not file size) run this command:
+
+{{{
+>$ gdal_translate -outsize 50% 50% "PG:host='localhost' dbname='<wktraster_database>' user='<wktraster_user>' password='<wktraster_password>' table='utm'" utm_half_size.tif 
+}}}
+
+This will create a file called ''utm_half_size'' like the original ''utm.tif'' but half size.

 == '''3.3 - Creating and modifying data''' ==
 
+The GDAL WKT Raster driver is not able to create and modify rasters yet. You'll have to use '''gdal2wktraster''' loader to create new ones.

-= '''5 - Reporting problems''' = 
+TODO
+
+
+= '''5 - Reporting problems''' =
+
+Take into account this driver '''is not part of the official GDAL library yet'''. Anyway, if you use it and find any error, if you want to suggest something or if you simply want to say ''hello'' :-), write a mail to ''jorgearevalo at gis4free dot com''
