 when they browse [pub.dartlang.org][pubsite]. It should be simple plain text:
 no markdown or HTML. That's what your README is for.
 
+## Author/Authors
+
+You're encouraged to use these fields to describe the author(s) of your package
+and provide contact information. `author` should be used if your package has a
+single author, while `authors` should be used with a YAML list if more than one
+person wrote the package. Each author can either be a single name (e.g. `Nathan
+Weizenbaum`) or a name and an email address (e.g. `Nathan Weizenbaum
+<[email protected]>`). For example:
+
+{% highlight yaml %}
+authors:
+- Nathan Weizenbaum <[email protected]>
+- Bob Nystrom <[email protected]>
+{% endhighlight %}
+
+The authors of a [hosted package](#hosted-packages) will be displayed on
+[pub.dartlang.org][pubsite].
+
+## Homepage
+
+This is optional. It should be a URL pointing to the website for your package.
+For [hosted packages](#hosted-packages), this URL will be linked from the
+package's page on [pub.dartlang.org][pubsite].
