+Applications
+============
+
+
+Deploying
+---------
+To deploy a new application, connect a model and then call its
+:meth:`~juju.model.Model.deploy` method. An
+:class:`~juju.application.Application` instance is returned.
+
+.. code:: python
+
+  from juju.model import Model
+
+  model = Model()
+  await model.connect_current()
+
+  mysql_app = await model.deploy(
+      # If a revision number is not included in the charm url,
+      # the latest revision from the Charm Store will be used.
+      'cs:mysql-55',
+      application_name='mysql',
+      series='trusty',
+      channel='stable',
+      config={
+          'tuning-level': 'safest',
+      },
+      constraints={
+          'mem': 256 * MB,
+      },
+  )
+
+
+Adding Units
+------------
+To add units to a deployed application, use the
+:meth:`juju.application.Application.add_units` method. A list of the newly
+added units (:class:`~juju.unit.Unit` objects) is returned.
+
+.. code:: python
+
+    ubuntu_app = await model.deploy(
+        'ubuntu',
+        application_name='ubuntu',
+        series='trusty',
+        channel='stable',
+    )
+
+    unit_a, unit_b = await ubuntu_app.add_units(count=2)
+
+
+Updating Config and Constraints
+-------------------------------
+Example showing how to update configuration and constraints on a deployed
+application. The `mysql_app` object is an instance of
+:class:`juju.application.Application`.
+
+.. code:: python
+
+  MB = 1024 * 1024
+
+  # Update and check app config
+  await mysql_app.set_config({'tuning-level': 'fast'})
+  config = await mysql_app.get_config()
+
+  assert(config['tuning-level']['value'] == 'fast')
+
+  # update and check app constraints
+  await mysql_app.set_constraints({'mem': 512 * MB})
+  constraints = await mysql_app.get_constraints()
+
+  assert(constraints['mem'] == 512 * MB)

-Connecting to a Controller
-==========================
-A Juju controller provides websocket endpoints for itself and each of its
-models. In order to do anything useful, the juju lib must connect to one of
-these endpoints.
-
-Connecting to the controller endpoint is useful if you want to programmatically
-create a new model. If the model you want to use already exists, you can
-connect directly to it (see :doc:`connect-model`).
-
-
-To the Current Controller
--------------------------
-Connect to the currently active Juju controller (the one returned by
-`juju switch`). This only works if you have the Juju CLI client installed.
-
-.. code:: python
-
-  from juju.controller import Controller
-
-  controller = Controller()
-  await controller.connect_current()
-
-
-To a Named Controller
----------------------
-Connect to a controller by name.
-
-.. code:: python
-
-  from juju.controller import Controller
-
-  controller = Controller()
-  await controller.connect_controller('mycontroller')
-
-
-To an API Endpoint with Username/Password Authentication
---------------------------------------------------------
-The most flexible, but also most verbose, way to connect is using the API
-endpoint url and credentials directly. This method does NOT require the Juju
-CLI client to be installed.
-
-.. code:: python
-
-  from juju.controller import Controller
-
-  controller = Controller()
-
-  controller_endpoint = '10.0.4.171:17070'
-  username = 'admin'
-  password = 'f53f08cfc32a2e257fe5393271d89d62'
-
-  # Left out for brevity, but if you have a cert string you should pass it in.
-  # You can copy the cert from the output of The `juju show-controller`
-  # command.
-  cacert = None
-
-  await controller.connect(
-      controller_endpoint,
-      username,
-      password,
-      cacert,
-  )
-
-
-To an API Endpoint with Macaroon Authentication
------------------------------------------------
-To connect to a shared controller, you'll need
-to use macaroon authentication. The simplest example is shown below, and uses
-already-discharged macaroons from the local filesystem. This will work if you
-have the Juju CLI installed.
-
-.. note::
-
-  The library does not yet contain support for fetching and discharging
-  macaroons. Until it does, if you want to use macaroon auth, you'll need
-  to supply already-discharged macaroons yourself.
-
