 # About
 
 This is a _work-in-progress_ parser meant to deprecate the existing Ruby parser
-in `codegen/`. This project will progess over multiple stages (PRs).
-
-- [x] Write a (minimal) parser with full coverage of the C headers in `include/` ([#3065](https://github.com/trustwallet/wallet-core/pull/3065)).
-- [ ] Implement a templating engine, write easy to read templates.
-	- [ ] Start with Swift codegen, replicate existing API (no breakage).
-	- [ ] Complete codegen for remaining languages.
-- [ ] Extend the parser to handle all valid C header syntax.
-	- [ ] Add explicit error types (right now it's just `Error::Todo`).
-	- [ ] Seperate parser logic from C header grammer (no refactoring required, just reorganization).
-- [ ] Update the entire building system.
+in `codegen/`. As of now, we only support Swift binding generation. This project
+will progess over multiple stages (PRs).
 
 ## Execution
 
 ```bash
 $ cd codegen-v2
-$ cargo run
+$ cargo run -- swift
 ```
 
-This command reads the C headers in `include/` and generates a
-`include_manifest.json` file.
+The bindings are saved to `bindings/`.
