+We want to make program with iced for layershell and sessionlock, so we made this project.
 
 Take winit as reference a lot, to make easilier program on layershell and ext-session-lock.
 
 This project bind `ext-session-lock` and `layershell` with the similar way of winit, which storing message and handle it in callback

+#### Feature:
+
+- support to open new layershell and support popup window.
+- support ext-virtual-keyboard
+
+![example](./misc/iced_layershell_example.png)
+
+With crate, you can use iced to build your kde-shell, notification application, and etc.

 iced binding for sessionlock
+
+Session lock is the wayland protocol for lock. This protocol is supported in river, sway and etc. We use it make a beautiful lock program in [twenty](https://github.com/waycrate/twenty). You can also use it to build your sessionlock. This will become very easy to use our crate with pam crate.
+
+
+## Help Us
+
+in iced 0.13, there will be breaking changes, we need someone who are familiar with iced to help us. And text-input-v3 and input-method also not handled, we also need some help since ime feature will be support in iced 0.13, we think this feature is very important, we need prepare for it.

+xkbcommon is too difficult for me. I can just understand part of the code, but it works
