 # WAGMI (WebAssembly General & Minimal Interpreter)
-WAGMI is a minimalistic in-place WebAssembly interpreter written in Rust (WIP).
 
-Original idea: https://www.cs.tufts.edu/comp/150FP/archive/ben-titzer/wasm-interp.pdf
+WAGMI is a minimalistic in-place WebAssembly interpreter written in Rust, with full support for the [WebAssembly 1.0 core standard](https://www.w3.org/TR/wasm-core-1/).
 
-The spec test suite in this repo is from https://github.com/WebAssembly/spec/releases/tag/list
+Based on the [original paper by Ben L. Titzer](https://www.cs.tufts.edu/comp/150FP/archive/ben-titzer/wasm-interp.pdf).
 
-The associated `wast2json` and `wat2wasm` binaries are of version `1.0.13 (1.0.14)`, you can find the Windows version here: https://github.com/WebAssembly/wabt/releases/tag/1.0.15
+## Project Structure
 
-Newer tests/wast converter may not work since this project specifically targets the 1.0 core WebAssembly standard. There will not be active development beyond full 1.0 support.
+- `/src` - Core interpreter implementation
+  - `module.rs` - WebAssembly module parsing and structure
+  - `validator.rs` - Module validation logic
+  - `instance.rs` - Runtime instance and execution engine
+  - `wasm_memory.rs` - Linear memory management
+  - `signature.rs` - Function signature handling
+  - `leb128.rs` - LEB128 encoding/decoding utilities
+  - `byte_iter.rs` - Byte stream iteration helpers
+  - `error.rs` - Error types and handling
+  - `lib.rs` - Library entry point
+  - `/bin` - Example usage demonstrations
+- `/tests` - Tests
+  - `/spec_tests.rs` - Test runner
+  - `/core` - WebAssembly spec test suite
+- `/docs` - More detailed documentation
+
+## Testing
+
+The spec test suite is from the [WebAssembly specification repository](https://github.com/WebAssembly/spec/releases/tag/list). The `wast2json` and `wat2wasm` binaries used are version 1.0.13 (1.0.14) [Windows version available here](https://github.com/WebAssembly/wabt/releases/tag/1.0.15).
+
+**Note:** This project specifically targets the WebAssembly 1.0 core standard. Newer test converters may not be compatible. There is no plan for development beyond 1.0 support.
