+# 1-Wire search algorithm
+
+This project provides a reimplemented 1-Wire bus search algorithm 
+(used to identify e.g. DS18x20 thermometers on a common open-drain bus).
+
+The algorithm uses no global variables and allows finding 
+a unlimited number of bus devices.
+
+For an example of usage, see `main.c`.
