 # Support
 
-You can access our pro support if you subscribe to any of these plans:
+Xen Orchestra will run in a controlled/tested environment thanks to XOA ([Xen Orchestra virtual Appliance](https://xen-orchestra.com/#!/xoa)). **This is the way to get pro support**. Any account with a registered XOA can access a [dedicated support panel](https://xen-orchestra.com/#!/member/support).
 
+XOA is available in multiple plans:
+
+* Free  
 * Starter
 * Enterprise
 * Premium
 
-The better the plan, the faster the support will be with higher priority.
+Higher tier support plans include faster ticket response times (and cover more features). Paid support plans and response times are based on the plan you have, plans can be [reviewed here](https://xen-orchestra.com/#!/xo-pricing).

+## XOA Free support
+
+With the free version of the Xen Orchestra Appliance (XOA free), you can open support tickets and we will do our best to assist you, however, this support is limited and is not guaranteed in regards to response times or resolutions offered.

+
+> Note: support from the sources is harder, because Xen Orchestra can potentially run on any Linux distro (or even FreeBSD and Windows!). Always try to double check that you followed our guide on how to [install it from the sources](https://xen-orchestra.com/docs/from_the_sources.html) before going further.
