+# Prism
+
+A node-based image compositing tool. Images flow through a directed acyclic
+graph (DAG) of processing nodes (read, blend, colour-grade, etc.) and are
+rendered via GPU shaders.
+
+## Status
+
+Early development. Scaffolding and exploratory scratchpad work.
+
+## Language & Tooling
+
+- **Language**: C11 / C++11 (dual-mode), following conventions in `src/wapp/`
+- **GPU API**: Vulkan, abstracted behind a Rendering Hardware Interface (RHI)
+- **Shading language**: Slang (`src/shaders/`)
+- **Build**: TBD
+
+## Dependencies
+
+- `src/wapp/` — local utility library (vendored, provides allocators, arrays,
+  strings, platform abstractions, etc.)
