+# Getting Support
+
+ There are many ways to get help for questions and issues related to AMP:	
+
+ **Need help with AMP?**	
+
+ If you are looking for help to get started using AMP on your site or you are having issues using AMP, consult these resources:	
+
+ *   [Official documentation](https://amp.dev/documentation/guides-and-tutorials/) with guides and tutorials to help you learn about AMP.	
+*   [Hands-on samples and demos](https://amp.dev/documentation/examples/) for using AMP components.	
+*   [Pre-styled templates and components](https://amp.dev/documentation/templates/) that you can use to create styled AMP sites from scratch.	
+*   [AMP tools](https://amp.dev/documentation/tools) helping you get started with building AMP pages.	
+*   [AMP supported browsers](https://amp.dev/support/faq/supported-browsers) to learn which browsers support AMP.	
+*   [Stack Overflow](http://stackoverflow.com/questions/tagged/amp-html) is our recommended way to find answers to questions about AMP; since members of the AMP Project community regularly monitor Stack Overflow you will probably receive the fastest response to your questions there.	
+*   For AMP on Google Search questions or issues, please use [Google's AMP forum](https://goo.gl/utQ1KZ).	
+*   To check the status of AMP serving and its related services, see the [AMP Status](https://status.ampproject.org/) page.

+
+ **Contributing to AMP?**
