In this video tutorial I show how to georeference an ancient map in QGIS using Georeference GDAL.
The summary:
1. Prepare raster layer tha you want to georeference and other file with correct spatial reference (in my case a shapefile)
2. Add Ground Control Points (GCP) (at least 4)
3. Select transformation method, projection, output file
4. Finish
Enjoy ...
