+### Node.js packages
+
+Node.js packages should be built with the `nodejs` build style, if possible.
+The `nodejs` build style takes care of downloading yarn/npm dependencies
+and running builds via package.json scripts.
+
+The following template variables influence how Node.js packages are built:
+- `nodejs_build_script`: the package.json script that builds the app files
+	(default: `build`).
+- `nodejs_install_script`: app installing script, which most probably 
+	doesn't even exist and you should redefine `do_install`
+	in your build script. 
+- `nodejs_packager`: whether the build script should use yarn or npm.
+	Set to `yarn` if the `yarn.lock` file exists, else it's set to `npm`
+- `NODE_ENV`: set to `production` by default
