You should pay attention to the following points in order to create Open Code in a form that is easy for you and others to use right from the start:

• If possible, decide in favour of an open programming language (if it has not yet been determined), for example Julia, Python or R.
• Check whether a Code Notebook (such as a so-called Jupyter Notebook) or even a container environment is suitable for you.
• If you are working with others, select suitable tools or platforms for collaborative code development, such as GitHub or GitLab. Also consider the tips for working together on code.
• Name folders and files in a standardised and meaningful way (for tips, see).
• Make code understandable by ensuring good readability and documentation.
• Make the code FAIR.
• Determine how the code is versioned (version control).
• Decide how, where and when the code is published.
• Select a licence.
