+# km3mon
+
+Monitoring facility for the KM3NeT neutrino detector.
+
+## Requirements
+
+There are two requirements needed:
+
+ - Python 3.5+
+ - tmux
+
+Both of them should be available ony any DAQ system you encounter. If not,
+contact the administrators.
+
+Every other dependency will be installed or updated during the `make` procedure
+via the Python package manager `pip`.
+
+## Usage
+
+First, install (or update) the requirements by typing
+
+    make
+
+Next check out the `configure` options with
+
+    ./configure --help
+    
+which will print the following screen:
+
+```

+Usage:  ./configure [options]
+
+  OPTION                    DESCRIPTION                    DEFAULT
+  --detector-id             Detector ID                    29
+  --daq-ligier-ip           DAQ Ligier                     192.168.0.110
+  --daq-ligier-port         Port of the DAQ Ligier         5553
+  --monitoring-ligier-port  Port of the monitoring Ligier  5553
+  --tmux-session-name       TMUX session name              km3mon
+  --webserver-port          Port of the web server         8080
+
+All invalid options are silently ignored.
+```
+
+and configure the ``Makefile`` with
+
+    ./configure --your --options
+
