 > GPU Accelerated, Distributed, Actor Model Language
 
+This is project is a _Work In Progress_, nothing works yet.
+
 Goals:
 
 * Have code running on the GPU and CPU
 * Have code running across many machines
 * Use the actor model for concurrency
 
-This is very much a _Work In Progress_, nothing works yet.
-
-Roadmap:
-
-* Frontend
-    * [x] Lexer
-    * [ ] Parser _WIP_
-    * [ ] Start parsing imported modules immediately
-* Middle
-    * [x] AST Structure
-    * [x] Thread-safe IR Structure
-    * [x] Concurrent IR Symbol Resolution
-    * [x] AST Expression -> IR Instruction conversion
-    * [ ] Passes to validate things
-* Error messages
-    * [ ] Parser error messages
-    * [ ] Validation messages
-* Backend
-    * Normal Backends
-        * [ ] [CraneLift](https://github.com/CraneStation/CraneLift) _WIP_
-        * [ ] LLVM ([inkwell](https://github.com/TheDan64/inkwell) or [llvm-sys](https://crates.io/crates/llvm-sys))
-    * GPU Backends
-        * [ ] SPIR-V ([rspirv](https://github.com/gfx-rs/rspirv))
-        * [ ] CUDA ([libcuda](https://github.com/peterhj/libcuda))
-        * [ ] OpenCL (for older platforms?) ([ocl](https://github.com/cogciprocate/ocl))
-        * [ ] Dynamically figure out the best backend to use
-* Runtime
-    * [ ] Schedulers
-    * [ ] Cross-node communication
-    * [ ] GC for actors?
-* Really dig into semantics
----
-
-Language Ideas
-
-* Compile time code execution
-* Strong type system
-    * Algebraic Data Types
-    * Unique & Borrowed Types
-* Automatic Versioning
-    * Enforce public APIs
-* Clean syntax
-* Concurrent compiler pipeline
