Just a little comment on the documentation. As an ESL person, when reading https://docs.prefect.io/guide/core_concepts/states.html#state-types section I got confused a bit between state and state types. I'd propose changing it to:

"There are three main state types: Pending, Running, and Finished. Flows and tasks typically progress through these three states types. At each stage of the execution pipeline, the current state type determines what actions are taken.

Sorry if this seems like nitpicking! I don't mean to 🙂
