-Replace `<path-to-the.sif>` with the full path to your local apptainer image file.
+Replace `<path-to-the.sif>` with a path to the image you want to use for jupyter. For example, `<path-to-the.sif>` could be:
+- The full path to an image you've already built on SDF: For example, if you ran `apptainer build` in your home directory, the image path may be `/sdf/home/u/username/my-special-jupyter.sif`
+- A tag available publicly on a remote registry (for example, `docker://jupyter/datascience-notebook:lab-4.0.7`) would download and use [a specific version of Jupyter Lab](https://hub.docker.com/layers/jupyter/datascience-notebook/lab-4.0.7/images/sha256-9504f4f4ab7e89b49d61d7be2e9ff8c57870de2050aa4360f55b2e59193f7486?context=explore) already packaged into a container by Project Jupyter.
+  - Note: If you use this method, the image will still need to be downloaded onto SDF and will (by default) take up disk space in your home directory under `~/.apptainer` to store the resulting image.

+By default `apptainer` overrides your terminal prompt with `Apptainer> ` in order to emphasize that you are opening a terminal within a container.
+If you prefer a less stark reminder you may instead include the following lines in `~/.bashrc` for a more familiar prompt with a subtler `(apptainer)` prefix indicating the environment is within a container.
+```bash
+# add a prefix if this shell is in a container
+export PROMPT_COMMAND='[ -f /singularity ] && PS1="(apptainer) ${PS1}"; unset PROMPT_COMMAND'
+```
+This would make the terminals that you open in Jupyter Lab appear with your customary prompt, except for the additional `(apptainer) ` prefix.
