-Pugl is a library 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.
+Pugl is a minimal portability layer for embeddable GUIs.
+It provides a drawing context and event-based main loop API,
+which can be used to create graphical applications or embedded views.
 
-Pugl is particularly suitable for use in plugins or other loadable modules.
-It has no implicit context or mutable static data,
-so it may be statically linked and used multiple times in the same process.
-
-Pugl has a modular design with a core library and separate graphics backends.
-The core library implements platform support and depends only on standard system libraries.
-MacOS, Windows, and X11 are currently supported as platforms.

 Pugl includes graphics backends for Cairo_, OpenGL_, and Vulkan_.
 Other graphics APIs can be used by implementing a custom backend.
