-Join us for a comprehensive hands-on lab that will take you from Slang basics to advanced features. This is an interactive session.
+Join us for an introductory lab for the Slang shading language, covering topics from language basics to advanced features like generics and automatic analytical derivatives.
+
+We'll also have a few small projects and coding puzzles so you can try out what we'll be talking about, using a new shader editor built for this lab! We'll also demo how Slang works with debuggers like RenderDoc, and port a GLSL shader live. The room will have computers, so no need to bring a laptop.

+You can also download the full lab materials and slides below!
