+Getting Started
+===============
+
+Setting up a basic application
+------------------------------
+
+Dashing lets you create elegantly tiled interfaces for your terminal application user interface (TUI). Create your TUI
+by constructing a suitable root :class:`.Tile`. The simplest possible example would be to create a single :class:`.Text` tile:
+
+.. code-block:: python
+
+    from dashing import Text, open_terminal
+
+    ui = Text(text="Hello World, this is dashing!", color=0)
+
+    with open_terminal() as terminal:
+        ui.display(terminal)
+        input("\nPress Enter to quit")
+
+You should see the Dashing TUI open, display the application, wait for input, and then clean itself up.
+
+.. warning::
+
+  We use color ``0``, black, which might not contrast enough with your terminal's color to be visible! Try another number
+  between 0-7 (included) if you don't see anything.
+
+
+.. admonition:: Note - Terminals
+  :class: note
+
+  We use the :func:`.open_terminal` helper to open an underlying Blessed terminal. If you wish to integrate Dashing into
+  an existing Blessed application, you can simply pass an existing ``Terminal`` object. Without using a proper Terminal
+  context, calls to ``ui.display()`` may leave the user's terminal in a messy state!
+
+The power of Dashing shines when you combine it with an event loop, and make periodic calls to ``ui.display()`` to
+update and redraw the screen.
+
+Let's create an application with a title, border, and 2 horizontal gauges that increment decrement for a couple of
+seconds:
+
+
+.. code-block:: python
+
+    from dashing import HGauge, HSplit, Text, open_terminal
+
+    ui = HSplit(
+         HGauge(),
+         HGauge(val=100),
+         border_color=3,
+         title="My First App"
+    )
+
+    with open_terminal() as terminal:
+        for i in range(100):
+            ui.items[0].value = i % 101
+            ui.items[1].value = (100 - (i % 101))
+            ui.display(terminal)
+            time.sleep(1 / 25)
+
+As you can see, Dashing added a border and a title around the root tile, and periodically redraws the screen with the
+new values.
