Can you update the page in various places to make it clear that this is for Gazebo Classic?
It's confusing to search for "gazebo tutorials" hoping to find stuff for the new gazebo, but then come here instead.

• Repo About
  • change "Tutorials for gazebo" to "Tutorials for gazebo classic"
• README Title
  • change "Gazebo Tutorials" to "Gazebo Classic Tutorials"
