# Pseudo States In UML2 whe have a number of what we call pseudo states. Examples of pseudo states are: * [fork](/states/concurrent-states/fork.md) * [join](/states/concurrent-states/join.md) The FSM can never be said to be in a Pseudo states. The StateMachine always transitions through pseudo states instantaneously. We do not emmitt pseudo states into the StateOfMind [stream](/tracking-state/stream-of-states.md) nor transitions. Instead you will see an transition from the original state into the target state. FSM2 models the above pseudo states as transitions as that is where the fit naturally into the FSM2 builder pattern. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://fsm2.onepub.dev/states/pseudo-states.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
