+* **sbt** - a convenience script to avoid any manual install. Will check for dependencies (Java, Scala, libraries) and automatically download files. Not needed if SBT is already installed via hmoebrew, apt-get, MSI etc.
+* **src/main/scala/test/Main.scala** - a println for Hello World message
+* **project/Buid.scala** - sets some compiler flags and the project name
+
+
+## Command line
+
+* **sbt help** - SBT usage help
+* **sbt help tasks** - available task list: clean, compile, run, package, test etc.
+* **sbt console-quick** - starts the Scala REPL
+* **sbt console** - starts the Scala REPL with the current project in the classpath
+* **sbt run** - runs the active project (in this case prints "Hello World")
+* **sbt package** - creates a JAR file in the "target" folder (size: about 1.5K)
