+# Introduction
+
+This is a template software project repository used by the [Intermediate Research Software Development Skills In Python](https://github.com/carpentries-incubator/python-intermediate-development).
+
+## Purpose
+
+This repository is intended to be used as a code template which is copied by learners at [Intermediate Research Software Development Skills In Python](https://github.com/carpentries-incubator/python-intermediate-development) course.
+This can be done using the `Use this template` button towards the top right of this repo's GitHub page.
+
+This software project is not finished, is currently failing to run and contains some code style issues. It is used as a starting point for the course - issues will be fixed and code will be added in a number of places during the course by learners in their own copies of the repository, as course topics are introduced.
+
+## Tests
+
+Several tests have been implemented already, some of which are currently failing.
+These failing tests set out the requirements for the additional code to be implemented during the workshop.
+
+The tests should be run using `pytest`, which will be introduced during the workshop.
