 # Long Term Support
 
-To provide stability to Altis users, major Altis releases will be supported for a minimum of one year after their release. The latest release of Altis will receive full support, while older releases will receive support under the "long-term support" policy.
+To provide stability to Altis users, major Altis releases will be supported for a minimum of one year after their release. The latest release of Altis will receive full support, while older releases will receive support under the ["long-term support" policy](#long-term-support-policy).

 At all times, only a single major Altis version is fully supported, and is the "active" release. When a new major version of Altis is published, the previously active release moves into long-term support mode.
