An application usually combines 1 Platform backend + 1 Renderer backend + main Dear ImGui sources.

Omar: "I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."

READ FIRST
----------
- Remember to read the FAQ (https://www.dearimgui.org/faq)
- Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki)
- Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction or
destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs.
- Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
- The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
- Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in the FAQ.
You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki.
- Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI,
where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.

A: - Businesses: please reach out to "contact AT dearimgui.com" if you work in a place using Dear ImGui!
We can discuss ways for your company to fund development via invoiced technical support, maintenance or sponsoring contacts.
This is among the most useful thing you can do for Dear ImGui. With increased funding, we can hire more people working on this project.
- Individuals: you can support continued development via PayPal donations. See README.
- If you are experienced with Dear ImGui and C++, look at the GitHub issues, look at the Wiki, read docs/TODO.txt
and see how you want to help and can help!
- Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
You may post screenshot or links in the gallery threads (github.com/ocornut/imgui/issues/3488). Visuals are ideal as they inspire other programmers.
You may post screenshot or links in the gallery threads. Visuals are ideal as they inspire other programmers.
But even without visuals, disclosing your use of dear imgui helps the library grow credibility, and help other teams and programmers with taking decisions.
- If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on GitHub or privately).
