+# MSc thesis code in Git

+Following the [open science requirements](https://3d.bk.tudelft.nl/courses/geo2020/openscience/), it is now mandatory to release your code as open-source and to document it.
+
+You should first make sure that you have [all the ingredients of a good Git repository](/git/goodgit/), and then you can have a look at 4 good examples of repositories from MSc students:
