+# Snowtam decoder
+
+## Description
+
+Decoding a SNOWTAM is something that most pilots do on a regular basis, especially when they frequently fly in extremely cold weather conditions. 
+Therefore, it makes sense to provide these pilots with a tool that will help them decode the report quickly and accurately.
+
+The solution is a simple and intuitive android application using airport codes in ICAO format entered by the user, 
+it will search for SnowTam, decode them and display them via an interface. The application will take into account the search and display the location of the airport.
