+- `nodejs` For apps made in Node.js that get built with npm or yarn
+(including Electron.js apps). The variable `nodejs_build_script` must be set
+to the package.json script that builds the app files (default: `build`).
+The variable `nodejs_install_script` must be set to app installing script,
+which most probably doesn't even exist and you should redefine `do_install`
+in your build script. The variable `nodejs_packager` is set to `yarn`
+if the `yarn.lock` file exists, else it's set to `npm`, but you can overwrite it.
+`NODE_ENV` is set to `production` by default.

 - `R-cran` For packages that are available on The Comprehensive R Archive
 Network (CRAN). The build style requires the `pkgname` to start with
 `R-cran-` and any dashes (`-`) in the CRAN-given version to be replaced
