+# COMMANDS #
+############
+
+# 1. In general it's not recommended to run commands one by one, because sbt startup is quite slow
+# 2. Only commands without arguments are completed, because any commands with args have to be quoted: `sbt "show key"`
+# 3. Only those commands are completed that could be useful to run as one off, like `sbt new ...`, the rest should be run in an interactive sbt shell
+# 4. Tasks is somewhat dynamic and depends on the project definition, so only most common are offered
+# 5. Same about settings (none are offered)
+
+# These commands can be combined in any order
