+# I-Ching
+
+The I-Ching (a.k.a. the *Book of Changes*) is an ancient method of divination based on
+cleromancy (assigning meaning to the generation of apparently random numbers.) Six numbers
+between 6 and 9 are generated in order to create a hexagram, the meaning of which is
+contained in the I Ching book.
+
+You can find lots of great information on the 2000+ year history of the I-Ching on
+[Wikipedia](https://en.wikipedia.org/wiki/I_Ching)
+
+This app will send an I-Ching horoscope to the pre-configured mailhog instance in configurable intervalls.
+
+This app uses the I-Ching library app https://github.com/Velfi/i-ching.git.
+
+## Configuration
+It is possible to configure the intervall of days between the sending of horoscopes and the time of sending.
