+Pugl is an API for writing portable and embeddable GUIs.
+Pugl is not a toolkit or framework,
+but a minimal portability layer that sets up a drawing context and delivers events.
+Compared to other libraries,
+Pugl is particularly suitable for use in plugins or other loadable modules.
+There is no implicit context or static data in the library,
+so it may be statically linked and used multiple times in the same process.
+Pugl has a modular design that separates the core library from graphics backends.
+The core library is graphics agnostic,
+it implements platform support and depends only on standard system libraries.
+MacOS, Windows, and X11 are currently supported as platforms.
+Graphics backends are separate so that applications only depend on the API that they use.
+Pugl includes graphics backends for Cairo_, OpenGL_, and Vulkan_.
+It is also possible to use some other graphics API by implementing a custom backend,
+or simply accessing the native platform handle for a window.
