 ## Building the library
-1. Make sure you have nodejs installed and the `build-essential` package if using ubuntu.
-2. Install wasm-pack
+1. Install `wasm-pack`
 ```
 curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
 ```
+2. Install `cargo-make`
+```
+cargo install cargo-make
+```
 3. Compile zerokit for `wasm32-unknown-unknown`:
 ```
 cd rln-wasm
-wasm-pack build --release
+cargo make build
 ```
 
 ## Running tests
 ```
 cd rln-wasm
-wasm-pack test --node --release
+cargo make test
+```
+
+## Publishing a npm package
+```
+cd rln-wasm
+cargo make login
+cargo make publish
 ```
