"Getting Started" guide feedback

The Getting-Started Wiki is very confusing. I think that just base installation should be moved to different section and other examples should be linked at end.

I opened the wiki, and got confused.

1. The section game_loop, compiling/linking being before the Setting Up felt like a wall.
2. The setting up section feels so confusing to getting started with installation: branch part is in compiling/linking. The instructions felt so unclear, it would be nice if there was just step-by-step verbose guide rather that this.

Just getting started feels like a headache, so that section should be crystal clear.

Example Getting Started:
1.1 Installation (Step-by-step)
1.2 First example (Very simple one)
1.3 How it works
1.4 Links to other specific examples.

That is it for my 2 cents. Maybe this is an issue for me only.

Thank you for your feedback!

I have added a "Checking Out" section above "Compiling/Linking", moved two steps there, and made minor amends.
But otherwise I am not sure what precisely to do better.

My guess is that the 9 points list in "Setting up Dear ImGui & Backends" is mostly noise, and it is better to simply read any "Example: if you are using XXX" section. Maybe I should remove this section completely?

The point list feel like a noise but direct example will be harder to follow without some kind of flow.

1. It would be really helpful to know the flow of program. So just a high level architecture of a main.cpp file.

2. It would be nice it there was an platform agnostic example to just print something on the screen for the setup.

3. Instead of this like titles: "Example: If you are using Raw Win32 API + DirectX11", what it does should also be included, I think.

Section like this maybe?

## Example: What the program does
### Windows Specific
- Using Raw Win32API + DirectX11
    Source code link: ... 
    Description....
- Using Raw Win32 API + DirectX12
    ...

### Platform independent: ...
- Using GLFW + OpenGL/WebGL
...

I guess it would depend on how user uses DearIMGui so, I am not completely sure about example section. Like for me, who plans to use it for app/game development, it would be nice to get a setup and understand how it would work with some simple examples. But for people using it for other purposes, maybe it needs other specific examples.
