 ## A note on error handling and reporting
 
 The RFC states that errors in the templates could optionally be handled and reported to the user. This implementation takes a slightly different approach in that it tries to do a best effort template expansion and leaves erroneous expressions in the returned URI instead of throwing errors. So for example, the incorrect expression `{unclosed` will return `{unclosed` as output. The leaves incorrect URLs to be handled by your URL library of choice.

+## Supported Node.js versions
+
+The same versions that are [actively supported by Node.js](https://github.com/nodejs/release#release-schedule) are also supported by `url-template`, older versions of Node.js might be compatible as well, but are not actively tested against.
