 ==== Overview ====
 We are developing the Best Freakin' Home Screen Ever for release with version 1 of the AGL distribution.
+This project is covered by [[https://jira.automotivelinux.org/browse/SPEC-24?filter=10100 | Jira issue SPEC-24]] and its substasks.
 ==== Requirements ====
-Requirements for the Home Screen application are based on the [[:agl_specification|AGL Requirements Specification]]. The team pulled the requirements from the spec and determined which requirements are to be met during this development cycle (through the end 2015). That list of requirements is {{:agl-distro:demo-apps:agl_spec_homescreen_rev01.pdf|here}}.
+Requirements for the Home Screen application are based on the [[:agl_specification|AGL Requirements Specification ver 1.0]].
+**//Summary of Home Screen Requirements//**
+  * Customize GUI layout by each vehicle, grade, brand and so on.
+  * Display status notifications, pop-up window, system setting, software keyboard for ivi-use.
+  * Manage applications (menu screen, kick applications launcher, install applications)
+  * Switch applications ( application stack, last application)

 ==== Architecture ====
+**//Comparing ivi-shell to desktop-shell//**
+A shell consists of two components.
+  * Plugin: provided as the weston plugin
+  * Daemon: GUI for the system.
+Weston provides two type of plugins.
+  * desktop-shell: for PC use sample.
+  * ivi-shell: for ivi use provided by GENIVI.
+|          ^ desktop-shell  ^ ivi-shell                  ^
+^ Plug-in  | Standard APIs              | APIs for ivi-applications  |
+^:::       | APIs for desktop creation  | APIs for HMI control daemon|
+^:::       |                            | Layer control functions    |
+^ daemon   | GUI Design                 | GUI Design                 |
+^:::       | Application Launcher       | Application Launcher       |
+^:::       |                            | Layout, layer definition   |
+**Tizen Wiki**([[https://wiki.tizen.org/wiki/IVI-Shell]])\\
+IVI-Shell does not support "wl_shell" nor "xdg-shell" (the "desktop" shell protocols found in upstream Weston) but a totally different one, named "ivi-application".
+This means that standard Wayland clients cannot be displayed on IVI-Shell, unless they somehow use the IVI-Shell protocol. The package itself provides demo clients, but incompatible clients are more common.\\
+Which plugin should AGL homescreen use?
+  * Opt.1: re-use ivi-shell
+{{:agl-distro:demo-apps:option1.png?300|}}
+  * Opt.2: create a new shell for AGL
+{{:agl-distro:demo-apps:option2.png?300|}}
+|          ^ Pros                        ^ Cons                       ^
+^ Option 1 | ivi-shell upstream already  | Standard API Support needs to be added        |
+^:::       | Layer functionality available  | APIs for HMI control daemon                |
+^ Option 2 | Standard API support available | Need to create new software                |
+^:::       |                                | Layer functionality needs to be designed   |
+The team prefers to reuse ivi-shell (option 1) assuming the maintainer supports AGL changes.
+  * Support standard APIs
+  * Maintain and support AGL requirements
