 ### Tooling
 
 #### Emscripten
-A powerful compile
+*Disclaimer: pros/cons from a newbie's point of view. Highly experienced proffesionals may have a different perspective*
+
+pros:
+- battle tested
+
+cons:
+- steep learning curve
+- overwhelming docs
+- setting up everything can be awkward
+
 #### wasm-rust
+pros:
+- no extra tooling, just the Rust compiler
+- [`wasm-bindgen`](https://rustwasm.github.io/wasm-bindgen) a more high level approach of JS ⇔ interaction
+- easy setup
+
+cons:
+- bleeding edge-ish, still under development (need Rust beta)
 
 ### Rust
 Everything is immutable by default.
