+# Check SMHI Warn #
+This is a Nagios plugin that checks SMHI 
+(Sveriges meteorologiska och hydrologiska institut) for weather alerts. For 
+class 1 warning, the scripts exit with a warning state, for class 2 and 3
+it exit with a critical-state. In the rare cases where more than one warning
+is issued for the same area, the script exit with a critical state and a message
+that more than one warning is issued for the area.
+
+## Usage ##
+The script only takes one argument, the area/district for which it should check
+for weather alerts. The district must be entered exactly as it is on the SMHI
+webpage. For a complete list, enter 'list' instead of a district for argument.
+Don't forget to quote the district in the argument, such as the below example.
+
+    check_smhiwarn.php 'Skåne län utom Österlen'
+
+Create one instance of each district you want to monitor.
