- Add the Dear ImGui source files to your projects, using your preferred build system.
|

It is recommended you build the .cpp files as part of your project and not as a library.
|
||||
- You can later customize the imconfig.h file to tweak some compilation time behavior, such as integrating imgui types with your own maths types.
|

- See examples/ folder for standalone sample applications. To understand the integration process, you can read examples/opengl2_example/ because

it is short, then switch to the one more appropriate to your use case.

- See examples/ folder for standalone sample applications.
|

- You may be able to grab and copy a ready made imgui_impl_*** file from the examples/.
|
||||
- When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
