-//    )

-// Assertions

+//
+// # Assertions
 //
 // The `require` package have same global functions as in the `assert` package,
 // but instead of returning a boolean result they call `t.FailNow()`.
+// A consequence of this is that it must be called from the goroutine running
+// the test function, not from other goroutines created during the test.
 //
 // Every assertion function also takes an optional string message as the final argument,
 // allowing custom error messages to be appended to the message the assertion method outputs.
