title: JupyterLab User Settings File
body: <p>I leverage Docker containers to launch JupyterLabs and would like the ability to apply user settings directly at launch, instead of configuring user settings through the "Advanced Settings Editor" GUI at every container launch. </p>
  
  <p>In reviewing the following pull request, it does seem that this functionality should exist: <a href="https://github.com/jupyterlab/jupyterlab/pull/2585" rel="noreferrer">https://github.com/jupyterlab/jupyterlab/pull/2585</a></p>
  
  <p>I have not found anything referencing this capability in the JupyterLab documentation, so any leads would be greatly appreciated!</p>
