-## Compiling for WASM
+## Contributing
 
-Install [wasm-pack](https://rustwasm.github.io/wasm-pack/book/)
+### Modify
 
-```bash
-wasm-pack build --target web --no-default-features
-```
+Any Rust file you wish to modify can be found in `src/` with some tests in `tests/proj4js_tests.rs`.
+In order to test your new code, you need to build it thanks to WASM. More information on how to build it can be found in [README_WASM.md](./README_WASM.md).
 
-Or if you have installed [cargo-make](https://sagiegurari.github.io/cargo-make/), use the following
-command:
+### Test
 
-```bash
-cargo make wasm
-```
-
-### Running the WASM example
-
-There is a [`index.html`] file for testing the WASM module in a navigator.
-
-For security reasons, you need to run it from a server.
-You can start a Python server with the following command:
-
-```bash
-python3 -m http.server
-```
-
-The server will automatically serve the `index.html` file in the current directory.
-
-
-## Build for npm
-
-```
-cargo make wasm_bundle
-```
-
-This will create a npm bundler package in pkg-bundler
+If you want to test your code, you can ron locally some demos by reading [this README](./ol-proj4rs-demo-app/README.md) in `ol-proj4rs-demo-app/`.
+You can create another demo page with a HTML file + JavaScript file combo.
