 ## Features
 
 - Simple to use: commands `gpuresource` and `submit` are all your need
-- Automatically choose available GPUs among all the servers
-- interactively: just as the job is running in your local machine
-    + Display the output of the job in real time
+- Two modes: noninteractive mode, and interactive mode
+- Noninteractive mode: the job will be running in the background of the server
+    + You can turn off your local machine
+- Interactive mode: just as the job is running in your local machine
+    + Display the output of the program in the terminal of your local machine in real time
     + Kill the job by Ctrl-C
-    + Save the output in a log file
-    + Transfer back the files you specified

+1. Copy the code to the server.
+1. Run the job on it in noninteractive mode (default) or interactive mode (with `-i`).
+1. Save the output in a log file.

 - `jobfile` : File to be run
 - `jobname` : Job name, and also the folder name of the job. If not provided, a random number will be used.
 
 Options:
 
 - `-h`, `--help` : Show this help message and exit
+- `-i`, `--interact` : Submit as an interactive job
 - `-s SERVER`, `--server SERVER` : Server host name
 - `--gpuid GPUID` : GPU ID to be used; -1 to use CPU only
