+## Jupyter Notebook and JupyterLab
+
+You can build isolated containers with Juypter Notebook and JupyterLab.
+
+### Building a Notebook Image
+
+#### Using the default environment file `notebook.yaml`
+
+```bash
+# This will build <username>/notebook:latest
+./build.sh -n
+```
+
+#### Using one of the pre-defined environment files
+
+```bash
+# This will build <username>/notebook:dataviz from dataviz.yaml
+./build.sh -n dataviz
+# This will build <username>/notebook:openai from openai.yaml
+./build.sh -n openai
+```
+
+#### Using your own environment file
+
+1. Copy `notebook.yaml` to a new YAML file (e.g. `foo.yaml`) and add modules as needed.
+2. Build the image with
+```bash
+# This will build <username>/notebook:foo from foo.yaml
+./build.sh -n foo
+```
+
+### Creating an Alias `nbh` (for 'notebook here')
+
+Add the following lines to your `.bash_profile` file, like so:
+
+```bash
+# ~/foo/bar/py4docker/ is the absolute path to the project in this example
+alias nbh="bash ~/foo/bar/py4docker/run_notebook.sh"
+```
+**Warning:** 
+1. An alias will allow you to run the notebook container from any folder on your system, and that folder will be available for read- and write-access to all code and libraries inside the container.
+2. Symbolic links may allow access to resources outside the current working directory!
+
+#### Starting a Notebook Container
+
+The notebook containers need write-access and a network connection and are hence not as well isolated as in the Python script modus.
+
+The current working directory will be mapped to `/usr/app/src` inside the container.
+
+For a list of available notebook images (=environments), you can use the alias `nbh`
+
+```bash
+nbh --list
+```
+
+or
+
+```bash
+./run_notebook.sh --list
+```
+
+#### Using the default environment `notebook.yaml`
+
+```bash
+# This will start <username>/notebook:latest 
+nbh
+```
+
+#### Using one of the pre-defined environments
+
+```bash
+# This will start <username>/notebook:dataviz
+nbh dataviz
+# This will start <username>/notebook:openai
+nbh openai
+```
+
+#### Using your own environment
+
+```bash
+# This will start <username>/notebook:foo built from foo.yaml
+nbh foo
+```

 More advanced settings are possible, e.g. adding a proxy or firewall inside the container that permits access only to a known set of IP addresses or domains and / or logs the outbound traffic.
 
+## Updating
+
+For updating the Python packages, you should re-built the respective image with `-f` (for 'force'):
+
+```bash
+# Script
+./build.sh -f
+# Script development image
+./build.sh -f -d
+# Default notebook image
+./build.sh -fn
+# Notebook image from dataviz.yaml

+# Notebook image from openai.yaml
+./build.sh -fn openai

 ## Limitations and Ideas for Improvement
 
 - The code is currently maintained for Docker Desktop on Apple Silicon only. It may work on other platforms, but I have no time for testing at the moment. It seems to work on Debian.
-- Expand support for blocking and logging Internet access e.g. by domain or IP ranges is a priority at my side, but non-trivial.
+- Better support for blocking and logging Internet access e.g. by domain or IP ranges is a priority at my side, but non-trivial.
+- The Jupyter Notebook mode has currently no support for bind mounts in Linux file-systems and will hence only work with Docker Desktop.
+- Jupyter Notebook requires a writeable OS.
+- The image size can likely be reduced further.
