+### Personal States
+
+You can use your card10 to communicate your personal state to others, and find out about the state of others. 
+There are four states indicating that you want to have time to yourself, feel communicative, want to discover new things, or are occupied with camp(ing) tasks.
+Four personal states are defined:
+*  _______ red red, continuously on: **no contact, please!**
+*  . _ . _ blue led, short blink, long blink: **chaos**
+*  _ _ _ _ green led, long blinks: **communication**
+*  <> <> < yellow led, fade on and off: **camp**
+
+The mode can be activated via a card10 app, and is indicated with the top left LED lighting up the space between the fundamental and the harmonic board.
+You can also implement it on paper, if you run out of battery, by indicating the colour/modename/blinking pattern
+**Please respect the 'no contact, please' state of others.**
