cat <<STEPS
-----------------------
Awesome! MMT installed!
-----------------------
Working directory is '$MMT_HOME'.
Now you need to do some manual steps.

1)
  A extract-phase connection script needs to be created and configured to make a
  connection to the Voyager DB server and extract data.
  You can find examples in $EXTRACTOR_DIR
  You must edit/create a script and configure MMT to use it.
  Set
    $CONFIG_MAIN -> exportPipelineScript
  to point into the extract-phase triggering script.

  A default script is placed for you into a default position.

  If you don't have access to the Pretty* database, but have to rely on 3rd
  party DB dumps,
  $MMT_HOME/preproces.sh -script can be a good starter to do preprocessing to make the
  dumps work with MMT's Transform-phase

2)
  A load-phase (import) connection script needs to be created and configured to
  make a connection to the Koha application server and load data in.
  You can find examples in $LOADER_DIR
  You must edit/create a script and configure MMT to use it.
  Set
    $CONFIG_MAIN -> importPipelineScript
  to point into the load-phase triggering script.

  A default script is placed for you into a default position.

3)
  You probably want to version control your MMT configuration at '$MMT_HOME'
  A default .gitignore has been provided.
