+## When Not To Use It
+
+If you don't care about errors or output of some observables in your project, you may not need this rule.
+Alternatively, you may require all logic to go in the `pipe` section of your observables.
+In that case, you should not use this rule and should enable `no-subscribe-handlers` instead, which is the opposite of this rule.
+
+Type checked lint rules are more powerful than traditional lint rules, but also require configuring type checked linting.
