-## Important News!
-_(If you are using raw jars, you can skip this section.)_<br>
-Because of [JCenter shutdown](https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/) library has moved to Maven Central.
-That fact affects nothing, but the groupId parameter in your Gradle and Maven configuration files.
-From version `1.80-1.5.0` use `io.github.spair` instead of `io.imgui.java`. See an updated [How To Use](#how-to-use) section for details.

-**<ins>Old versions will not be transferred to Maven Central and will become unavailable after JCenter goes down.</ins>**

 You can use this video as a basic step-by-step tutorial. It shows how to integrate binding with the usage of jar files. Gradle and Maven dependecies could be used for this purpose as well.

 ## Freetype
 By default, Dear ImGui uses stb-truetype to render fonts. Yet there is an option to use FreeType font renderer. Go to the [imgui_freetype](https://github.com/ocornut/imgui/tree/256594575d95d56dda616c544c509740e74906b4/misc/freetype) to read about the difference.
