 ## Usage
 
+If you would like to package this library to run in a standalone manner within, e.g. a webpage, similarly to how the old mymonero.com used this library, a script is provided to bundle everything for you. It's located at `bin/package_browser_js`. If you package the library in this manner, the resulting `mymonero-core.js` file can be included via a script tag. The index.js of the library will then be available as the global variable `mymonero_core_js`.
+
+Alternatively you can bundle the contents in any other manner you prefer, including directly accessing them via your favorite module system. 
+
+
 ### `hostAPI`
 
 Use the functions in the modules in `hostAPI` for convenience implementations of (a) networking to a MyMonero-API-compatible server, (b) constructing common request bodies, and (c) parsing responses.
