+### Providing support URL
+
+Synapse-Admin provides a support link in the main menu - `Contact support`. By default, the link points to the GitHub issues page of the project. You can change this link by providing a `supportURL` in the `config.json`.
+
+```json
+{
+  "supportURL": "https://example.com/support"
