+Sentinel for Detecting Trusted Root Keys
+========================================
+
+The module ``ta_sentinel`` implements A Root Key Trust Anchor Sentinel for DNSSEC
+according to standard :rfc:`8509`.
+
+This feature allows users of DNSSEC validating resolver to detect which root keys
+are configured in resolver's chain of trust. The data from such
+signaling are necessary to monitor the progress of the DNSSEC root key rollover
+and to detect potential breakage before it affect users. One example of research enabled by this module `is available here <https://www.potaroo.net/ispcol/2018-11/kskpm.html>`_.
+
+This module is enabled by default and we urge users not to disable it.
+If it is absolutely necessary you may add ``modules.unload('ta_sentinel')``
+to your configuration to disable it.
