+
+## Testing
+
+You'll need Scala `2.12.7` and sbt `1.2.6`.
+
+Start by entering the sbt shell:
+```
+$ sbt
+```
+
+To run a solution - for instance **day 1** - you can conveniently use the following command:
+```
+> day 1
+```
+
+The output will be printed to the console and stored to the corresponding file in `output/`.
