-## sbt project compiled with Scala 3
+# :memo: Archery simulator using the Montecarlo method.
+Homework for "Computer Simulations" class, a GUI software created with [ScalaFx](https://www.scalafx.org/), you can start installing [sbt](https://www.scala-sbt.org/).
 
-### Usage
+This is almost 80% pure functional, things like the view and the pseudorandom number generation can't be performed (easily) with a functional perspective.
+
+## How it works?
+As you know, in FP we can't just put a counter and add the results of each game or round or competitor, so we run *all the games* (by default, 20000) and put them into a list of games, later we operate over the list and create the results.
+
+### Performance?
+It's just trash! :sleepy:
+
+### Ejecution
+This project has been created with Scala 3 (also called Dotty), using sbt for the dependencies. You can compile the project with this command.
+```
+sbt compile
+```
+And for run the project!.
+```
+sbt run
+```
 
-This is a normal sbt project. You can compile code with `sbt compile`, run it with `sbt run`, and `sbt console` will start a Scala 3 REPL.
 
-For more information on the sbt-dotty plugin, see the
