 This project aims to generate go wrapper for Dear ImGui.
 
-It comes with a default backend with GLFW 3.3 and OpenGL 3.2.
+It comes with [several default backends](supported-backends) implemented.
 
-It works on macOS(arm64/x86), windows(x64), Arch Linux/KDE and Fedora Workstation 36, idealy other linux GUI should works but I don't have a linux machine to test it. Check out `examples`, cd in and `go run .`.

+
+## Setup
+
+There are several dependencies you might need to install on your linux machine.
+Take a look [here](https://github.com/allendang/giu#install)
 
 ## Current solution is:
-1. Use cimgui's lua generator to generate function and struct definition as json.
-2. Generate proper go code from the definition (via manual crafted go program `/cmd/codegen`).
-3. Use the backend implementation from imgui.
-4. Use github workflow to compile cimgui and glfw to static lib and place them in /lib folder for further link.

 ## Supported Backends
 
-In order to make it easy in use, cimgui-go implemented a few imgui backends.
-To see more details about using a specific backend, take a look at the [examples](./examples).
+In order to make it easy in use, cimgui-go implemented a few imgui backends. All of them are placed in `backend/` sub-packages.
+To see more details about usage of a specific backend, take a look at the [examples](./examples).
 
 We support the following backends:
-- [GLFW](./examples/glfw). **Note:**: It is disabled by default, use `enable_cimgui_glfw` go build tag to enable it.
-- [SDL2](./examples/sdl). **Note:**: It is disabled by default, use `enable_cimgui_sdl2` go build tag to enable it.
-- [Ebitengine](./examples/ebiten) (`import "github.com/AllenDang/cimgui-go/ebitenbackend"`).
+- [GLFW](./examples/glfw). (GLFW 3.3 + OpenGL)
+- [SDL2](./examples/sdl). (SDL 2 + OpenGL)
+- [Ebitengine](./examples/ebiten) (`import "github.com/AllenDang/cimgui-go/backend/ebitenbackend"`).
 
 **Important**: Remember that various solution use different C libraries that can conflict with each other.
 It is recommended to not enable e.g. GLFW and SDL backends at the same time as it may result in linker crash.
 
 ## Naming convention
 
 - For functions, 'Im/ImGui/ig' is trimmed.
+- `Get` prefix is also removed.
 - If function comes from `imgui_internal.h`, `Internal` prefix is added.
-- Struct fields (if any exported) are prefixed with word `Field`
 
 ## Function coverage
 Currently most of the functions are generated, except memory related stuff (eg. memory allocator, storage management, etc...).
