+## Infallible
+
+`Infallible` is another flavor of `Observable` which is identical to it, but is guaranteed to never fail and thus cannot emit errors. This means that when creating your own `Infallible` (Using `Infallible.create` or one of the methods mentioned in [Creating your first `Observable`](#creating-your-own-observable-aka-observable-sequence)), you will not be allowed to emit errors.
+
+`Infallible` is useful when you want to statically model and guarantee a stream of values that is known to never fail, but don't want to commit to using `MainScheduler` and don't want to implicitly use `share()` to share resources and side-effects, such as the case in [`Driver` and `Signal`](Traits.md#rxcocoa-traits).
+
 ### Life happens
 
 So what if it's just too hard to solve some cases with custom operators? You can exit the Rx monad, perform actions in imperative world, and then tunnel results to Rx again using `Subject`s.
