-                            Take a screenshot at every step during installation and copy the images over to <filename>/tmp/anaconda-screenshots</filename> after installation is complete. This is useful for documentation.
+                            Take a screenshot at every step during installation. These screenshots are stored in <filename class="directory">/tmp/anaconda-screenshots</filename> during the installation, and after the installation finishes you can find them in <filename class="directory">/root/anaconda-screenshots</filename>.

This is important, because if you do not use all required Kickstart options and the installation therefore does not begin automatically, you can go to the screens which were not automatically configured, perform any configuration you want. Then, when you press <guilabel>Done</guilabel> to continue, the screen will be captured including the configuration you just provided.
