 #### Requirements
 
 To use runtime via Qiskit you'll need to
 
-- be in the `ibm-q-internal/near-time/qiskit-runtime` provider
 - install the latest Qiskit release
 - install the special `qiskit-ibmq-provider` branch:
   `pip install git+https://github.com/jyu00/qiskit-ibmq-provider@runtime-real` 
 - has the `near-time-systems` role if you want to upload new programs.
 
-The only device setup for runtime is `ibmq_montreal`.
+#### Additional requirements for staging
