@@ -655,6 +655,8 @@ The following options are supported:
 * **prepend-autoloader:** Defaults to `true`. If false, the composer autoloader
   will not be prepended to existing autoloaders. This is sometimesrequired to fix
   interoperability issues with other autoloaders.
+* **github-domains:** Defaults to `["github.com"]`. A list of domains to use in
+  github mode. This is used for GitHub Enterprise setups.
 * **notify-on-install:** Defaults to `true`. Composer allows repositories to
   define a notification URL, so that they get notified whenever a package from
   that repository is installed. This option allows you to disable that behaviour.
