+  # Tour of Heroes: the vision
+
+  Our grand plan is to build an app to help a staffing agency manage its stable of heroes.
+  Even heroes need to find work.
+
+  Of course we'll only make a little progress in this tutorial. What we do build will
+  have many of the features we expect to find in a full-blown, data-driven application: acquiring and displaying
+  a list of heroes, editing a selected hero's detail, and navigating among different
+  views of heroic data.
+
+  The Tour of Heroes covers the core fundamentals of Angular.
+  We’ll use built-in directives to show/hide elements and display lists of hero data.
+  We’ll create a component to display hero details and another to show an array of heroes.
+  We'll use one-way data binding for read-only data. We'll add editable fields to update a model
+  with two-way data binding. We'll bind component methods to user events like key strokes and clicks.
+  We’ll learn to select a hero from a master list and edit that hero in the details view. We'll
+  format data with pipes. We'll create a shared service to assemble our heroes. And we'll use routing to navigate among different views and their components.
+
+  We’ll learn enough core Angular to get started and gain confidence that
+  Angular can do whatever we need it to do.
+  We'll be covering a lot of ground at an introductory level but we’ll find plenty of links
+  to chapters with greater depth.

+  ## The End Game
+
+  Here's a visual idea of where we're going in this tour, beginning with the "Dashboard"
+  view and our most heroic heroes:

+  img(src='/resources/images/devguide/toh/heroes-dashboard-1.png' alt="Output of heroes dashboard")
+
+:marked
+  Above the dashboard are two links ("Dashboard" and "Heroes").
+  We could click them to navigate between this Dashboard and a Heroes view.
+
+  Instead we click the dashboard hero named "Magneta" and the router takes us to a "Hero Details" view
+  of that hero where we can change the hero's name.

+  Clicking the "Back" button would return us to the "Dashboard".
+  Links at the top can take us to either of the main views.
+  We'll click "Heroes". The app takes to the "Heroes" master list view.

+  We click a different hero and the readonly mini-detail beneath the list reflects our new choice.
+
+  We click the "View Details" button to drill into the
+  editable details of our selected hero.
+
+  The following diagram captures all of our navigation options.

+  ## Up Next
+
+  We’ll build this Tour of Heroes together, step by step.
+  We'll motivate each step with a requirement that we've
+  met in countless applications. Everything has a reason.
+
+  And we’ll meet many of the core fundamentals of Angular along the way.
