Just copy "dooris" to a folder in your $PATH. I do:
cp ./dooris ~/bin/
You can copy the file to /usr/bin to make it available for all users but I don't. If you want that just run:
sudo cp ./dooris /usr/bin/
Configuration:
--------------
Configuration needs to be done before compiling. There are some parameters you can set in the head of the dooris.c file where variables are declared. A configuration file will at this point make no sense.
