+## Building executable
+
+1. Create a fat jar distribution:
+```
+./gradlew shadowJar
+```
+The output file is located in `build/libs/trapping-1.1.0-all.jar`
+
+2. Run cross-sections computations
+```
+java -cp trapping-1.1.0-all.jar ru.inr.mass.trapping.CrosssectionsKt
+```
+
+3. Run simulation:
+```
+./gradlew run   
+```
