+It should be trivial to set up your text editor to do this for you. If you use
+vim, add this to your vim configuration:
 
+```vimscript
+" Lvimrc
+" if .lvimrc exists in current or parent directory of the currently loaded file,
+" load it as config
+if filereadable('../.lvimrc')

+Testing

+When testing Elemental, please be sure to test it on a network of at least 
+3 instances of elemental. Please also be sure to have one of these instances 
+run **without** the patch you are testing, to be able to show that there is 
+a difference.
