-This hands-on lab introduces Slang, an open-source, open governance shading language hosted by Khronos that simplifies graphics development across platforms. Designed to tackle the growing complexity of shader code, Slang offers modern programming constructs while maintaining top performance on current GPUs.
+Join us for an introductory lab for the Slang shading language, covering topics from language basics to advanced features like generics and automatic differentiation.
+
+This lab also includes a few small projects and coding puzzles so you can try out what is presented, using a new shader editor built for this lab! We also demo how Slang works with debuggers like RenderDoc, and port a GLSL shader live.
