kernelspec: {
        display_name: ks.displayName,
        language: ks.language,
        name: ks.name
      },
      nteract: {

      }
    },

    nbformat_minor: 2
  };

  // NOTE: For the sake of expediency, all the logic to launch a new is

  contents
    // Create UntitledXYZ.ipynb by letting the server do it
    .create<"notebook">(serverConfig, props.baseDir, {
      type: "notebook"
      // NOTE: The contents API appears to ignore the content field for new
      // notebook creation.
      //

      // notebook for the user and redirect them after we've put in the
      // content we want.
      //
      // Amusingly, this could be used for more general templates to, as
      // well as introduction notebooks.

    .pipe(
      // We only expect one response, it's ajax and we want this subscription
      // to finish so we don't have to unsubscribe
