 ## Additional configuration
 
+### Experimental test suite level visibility support
+
+Test suite level visibility (TSLV) is available for `datadog-ci`` gem versions 0.6 and above.
+To enable it add the following line to Datadog configuration:
+
+```ruby
+Datadog.configure do |c|
+  #  ... usual ci configs ...
+  c.ci.experimental_test_suite_level_visibility_enabled = true
+end
+```
+
+This will enable visibility into how your test suites and test sessions behave, providing
+insights about performance and reliability on test suite/session level.

 ### Add tracing instrumentations
 
 It can be useful to have rich tracing information about your tests that includes time spent performing database operations
