positive.code: link:http://tinkerpop.apache.org[Apache TinkerPop™] is an open source Graph Computing Framework. Within itself, TinkerPop
  represents a large collection of capabilities and technologies and, in its wider ecosystem, an additionally extended
  world of link:http://tinkerpop.apache.org/#graph-systems[third-party contributed] graph libraries and
  systems. TinkerPop's ecosystem can appear complex to newcomers of all experience, especially when glancing at the
  link:http://tinkerpop.apache.org/docs/x.y.z/reference/[reference documentation] for the first time.
  
  So, where do you get started with TinkerPop? How do you dive in quickly and get productive? Well - Gremlin, the
  most recognizable citizen of The TinkerPop, is here to help with this thirty minute tutorial. That's right - in just
  thirty short minutes, you too can be fit to start building graph applications with TinkerPop. Welcome to _The
  TinkerPop Workout - by Gremlin_!

  Gremlin helps you navigate the vertices and edges of a graph. He is essentially your query language to graph
  databases, as link:http://sql2gremlin.com/[SQL] is the query language to relational databases. To tell Gremlin how
  he should "traverse" the graph (i.e., what you want your query to do) you need a way to provide him commands in the
  language he understands — and, of course, that language is called "Gremlin". For this task, you need one of
  TinkerPop's most important tools: link:http://tinkerpop.apache.org/docs/x.y.z/reference/#gremlin-console[The Gremlin Console].
  
  NOTE: Are you unsure of what a vertex or edge is? That topic is covered in the <<_the_next_fifteen_minutes, next section>>,
