+## Getting started with this pyglotaran and this repository
+
+For more detailed instructions on setting up pyglotaran, and usage instructions, refer to the [pyglotaran user manual](https://pyglotaran.readthedocs.io/) online.
+
+### Repository Quick-Start
+
+Ensure you have a working Python 3.10 (or later) installation, and use your preferred python package manager to install the following Python packages:
+
+- `pyglotaran` ([pip](https://pypi.org/project/pyglotaran/), [conda](https://anaconda.org/conda-forge/pyglotaran))
+- `pyglotaran-extras` ([pip](https://pypi.org/project/pyglotaran-extras/), [conda](https://anaconda.org/conda-forge/pyglotaran-extras))
+
+<sub>At a minimum version 0.7.1 of both packages is required</sub>
+
+When using VS Code, additionally the `ipykernel` package is needed (but VS Code will prompt for this).
+
+When using Jupyter Notebook in the browser, also install: `jupyterlab` ([pip](https://pypi.org/project/jupyterlab/), [conda](https://anaconda.org/conda-forge/jupyterlab)) and then run `jupyter lab` to start a jupyter server.
+
+Then use VS Code or Jupyter to open one of the .ipynb notebooks from one of the subfolders in this project.
