+We have tested the script under Debian testing 8.x, but your mileage may vary 
+- we have not tested intensive enough to give any guarantee. By the way: We 
+do not give any guarantee in any way.
+
+So at least now it would be wise perhaps to use the way better tested Debian 
+7.x branch.

 Please keep in mind that several packages will be installed via internet and 
 some more data files will be fetched via http, so an internet connection is 
 vital.

+script directory, and start it without options. It will download and install 
+any needed system packages and helper files needed to function.
+
+So:
+
+1. change into the script directory (.../setup-scripts/satellit_installer).
+2. Start the script: ./satellite-installer
+3. Read script output for eventual warnings.
+4. Log out and re-log in to trigger the dropped script, or simply reboot
+   and re-login (a reboot is not quite necessary, but will not hurt either)
+5. At the end of the dropped script choose 'y' to reboot, or do some other 
+   stuff, as long as you do not forget to reboot prior using the Satellite.
+
+
+4. What to do if the script has thrown any errors?
+
+Well, the error handling and especially the re-entry features are somewhat 
+rudimentary. If you use a virtual machine it would be perhaps fastest to just 
+reset the machine and try again. Please let us know about any errors 
+encountered.
+
+If resetting the machine to the prior state is not feasible, take following 
+steps in a terminal (commands to enter are denoted between '': 'command'):
+
+1. 'source includes/00-variables.inc'
+2. 'source includes/10-uninstall_packages.inc'
+3. 'source includes/10-purge_install.inc'
+4. call the function purge_install: 'purge_install' (CAUTION: This will purge 
+   the packets given in 00-variables.inc: PACKAGELIST_SERVER and 
+   PACKAGELIST_SCRIPT without regard whether they were installed prior the 
+   first script run and it will kill/delete any Mysql databases / Mysql 
+   installation most brutally).
+5. re-run the script.
+6. As said: Let us know about any errors.
