+### I want an example of X! ### 
+
+If X is a feature of the library, file away! If X is an example of using a specific service, the best place to go is to the teams for those specific APIs - our preference is to link to their examples rather than add them to the library, as they can then pin to specific versions of the library. If you have any examples for other APIs, let us know and we will happily add a link to the README above!
+
 ### Why do you still support 5.2? ###
 
 When we started working on the 1.0.0 branch we knew there were several fundamental issues to fix with the 0.6 releases of the library. At that time we looked at the usage of the library, and other related projects, and determined that there was still a large and active base of PHP 5.2 installs. You can see this in statistics such as the PHP versions chart in the WordPress stats: http://wordpress.org/about/stats/. We will keep looking at the types of usage we see, and try to take advantage of newer PHP features where possible.

+### How do I set a field to null? ###
+
+The library strips out nulls from the objects sent to the Google APIs as its the default value of all of the uninitialised properties. To work around this, set the field you want to null to Google_Model::NULL_VALUE. This is a placeholder that will be replaced with a true null when sent over the wire.
