 Though the aim of the Polymer library is to allow lots of flexibility and not get in your way, we work to standardize our elements to make them as toolable and easy to maintain as possible.
 
-All elements should follow the [Polymer element style guide](http://polymerelements.github.io/style-guide/), which defines how to specify properties, documentation, and more. It's a great guide to follow when building your own elements as well, for maximum standardization and toolability. For instance, structuring elements following the style guide will ensure that they work with the [`iron-component-page`](https://github.com/polymerelements/iron-component-page) element, an incredibly easy way to turn any raw element directly into a documentation page.

 #### Contributing Code to the Polymer library
 
-We follow the most common javascript and HTML style guidelines for how we structure our code - in general, look at the code and you'll know how to contribute! If you'd like a bit more structure, the [Google JavaScript Styleguide](https://google.github.io/styleguide/javascriptguide.xml) is a good place to start.

 Polymer also participates in Google's [Patch Rewards Program](https://www.google.com/about/appsecurity/patch-rewards/), where you can earn cold, hard cash for qualifying security patches to the Polymer library. Visit the [patch rewards page](https://www.google.com/about/appsecurity/patch-rewards/) to find out more.
 
 ## Unit tests
 
-All Polymer projects use [`web-component-tester`](https://github.com/Polymer/web-component-tester) for unit tests.
-The [`polyserve`](https://github.com/PolymerLabs/polyserve) utility is helpful for running tests in the browser.
+All Polymer projects use [`polymer-cli`](https://github.com/Polymer/tools/tree/master/packages/cli) for unit tests.
