 Implementing [Crafting interpreters](https://craftinginterpreters.com) for the
 [FHNW](https://www.fhnw.ch) [PL-Circle](https://github.com/fhnw-pl-circle).
 
+All dependencies for running the respective implementations are specified in the
+`flake.nix` files within the project folders (look for the key `buildInputs`).
+Though my recommendation is to use the provided
+[nix flakes](https://nixos.wiki/wiki/Flakes).
+
 ## [Java Implementation](./java/lox-interpreter/)
 
 Implementation of the tree-walk interpreter in java after the book.
 
 Run `mvn package` to create an executable jar file in the `target` directory and
 `mvn exec:java` to get a repl.
+
+## [Rust implementation](./rust/rox/)
