+Build dependencies
+------------------
+
+List of packages required to build and test the code:
+- glib (libglib2.0, 2.35.4 or later)
+- cmake (cmake, 2.8.9 or later)
+- gcovr (gcovr, 2.4 or later)
+- lcov (lcov, 1.9 or later)
+- google test (libgtest-dev, 1.6.0 or later)
+- cppcheck (cppcheck)
+
+Building the code
+-----------------
+
+The simplest case is:
+
+    $ cd indicator-session-X.Y.Z
+    $ mkdir build
+    $ cd build
+    $ cmake ..
+    $ make
+
+Running the tests
+-----------------
+
+    $ cd indicator-session-X.Y.Z
+    $ mkdir build
+    $ cd build
+    $ cmake ..
+    $ make
+    $ make test
+    $ make cppcheck
+
+Generating Test Coverage Reports
+--------------------------------
+
+    $ cd indicator-session-X.Y.Z
+    $ mkdir build-coverage
+    $ cd build-coverage
+    $ cmake -DCMAKE_BUILD_TYPE=coverage ..
+    $ make
+    $ make coverage-html
+
+Installation
+------------
+
+FIXME: not tested
+To get files that form part of an installation, run a "make install"
+in the build directory. By default, this installs them in the "install"
+subdirectory of the build directory. If you want to install into a
+different directory, use
+
+$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local # Or wherever...
+$ make release
+$ make install

+Indicator-Session is the the session menu indicator for Unity.
+Its behavior and features are listed at https://wiki.ubuntu.com/SystemMenu.
+
+For instructions on building and running built-in tests, see the INSTALL file.
+
+
+Notes for Client Renderers
+--------------------------
+
+Indicator-Session has two custom types: the Guest menuitem and User menuitems.
+Referencing the spec at ,https://wiki.ubuntu.com/SystemMenu.>, both have four
+visual components: (1) an Active Session Mark and the user's (2) icon,
+(3) name, and (4) Logged In Mark.
+
+== User menuitems can be recognized by their "indicator.switch-to-user" action.
+   Their four visual components are determined by:
+
+   1. You can test for the Action Session Mark by checking the action's state.
+      The state is a dicionary whose "active-user" key yields the current
+      session's owner's username. If it matches the username in this menuitem's
+      "target" attribute, show the Active Session Mark.
+
+   2. The icon is stored in the menuitem's "icon" attribute. If none is set,
+      the client should use a fallback icon such as "avatar-default."
+
+   3. The name is stored in the menuitem's "label" attribute.
+
+   4. You can test for the Logged In Mark by checking the action's state.
+      The state is a dictionary whose "logged-in-users" key will give
+      an array of usernames. If the array contains the username in this
+      menuitem's "target" attribute, show the Logged In Mark.
+
+== Guest menuitems can be recognized by their "indicator.switch-to-guest" action.
+   Its four visual components is determined by:
+
+   1. You can test for the Active Session Mark by checking the action's state.
+      The state is a dictionary whose "is-active" key yields a boolean.
+      If the booelan is true, show the Active Session Mark.
+
+   2. The guest user should use a fallback icon such as "avatar-default."
+
+   3. The name ("Guest") is stored in the menuitem's "label" attribute.
+
+   4. You can test for the Logged In Mark by checking the action's state.
+      The state is a dictionary whose "is-logged-in" key yields a boolean.
+      If the boolean is true, show the Logged In Mark.

+ *  SEAT / SESSION TRACKING
+ *
+ *  There are two simple goals here:
+ *
+ *   1. Keep track of how many GUI sessions each user has
+ *      so that we can set the 'is_logged_in' flag correctly
+ *
+ *   2. Also track which is the current session,
+ *      so that we can compare it to those GUI sessions to
+ *      set the 'is_current_session' flag correctly.
+ *
+ *  Now that you know the goals, these steps may make more sense:
+ *
+ *   1. create a ConsoleKitManager proxy
+ *   2. ask it for the current session
+ *   3. create a corresponding Session proxy
+ *   4. ask that Session proxy for its seat
+ *   5. create a corresponding Seat proxy
+ *   6. connect to that seat's session-added / session-removed signals
+ *   7. ask the seat for a list of its current sessions
+ *   8. create corresponding Session proxies
+ *   9. of them, look for the GUI sessions by checking their X11 properties
+ *   10. for each GUI session, get the corresponding uid
+ *   11. use the information to update our uid <--> GUI sessions tables
