This repository provides details on the metadata convention used in Jupyter notebooks for training developed for ECMWF. Please see the [Jupyter notebook template](https://github.com/ecmwf-training/jupyter-template/blob/develop/jupyter-notebook-template.ipynb) as an example of how this metadata is applied.
