 The content of NPM module published to repository is missing `index.js`, `index.d.ts` and _native library_ with SDK implementation. All these missig files are generated by [NAPI-RS](https://napi.rs/) during **package install time**. 
 
-When `cohort_sdk_js` NPM package is installed via `npm -i` the "postinstall" hook is invoking `cohort_sdk_js/scripts/postinstall.sh` which in turn compiles Rust code for your architecture, then generates JS code and moves files to their indended destinations so that we end up with finished working NPM package. All this happens on the client machine under `./node_modules/@kindredgroup/cohort_sdk_js`. The build process is verbose if installation is invoked with additional flag: `npm -i @kindredgroup/cohort_sdk_js@SOME_VERSION --forground-scripts`, otherwise native compilation happens in the background.
