+# Screaming Hot
+
+Make your computer scream when it gets hot !
+
+# Limitations
+
+This only handles temperature reading for Linux, as it is exposed by a simple file. Not tested on MacOS.
+
+# Usage
+
+Running the program without arguments will use default values set in code.  
+The two first arguments set the minimum and maximum temperature of the range, the third sets the number of samples for
+averaging it temperature readings and the fourth the file where temperature should be read from.
+
+Any other number of arguments or a number that cannot be parsed will print out the usage details.
+
+Pressing `Escape` will quit the application.
