+# Generation of FESOM Meshes
+
+This is a
+[cookiecutter](https://cookiecutter.readthedocs.io/en/1.7.0/README.html) for
+generating FESOM meshes. To use it, simply do:
+
+```shell
+$ cookiecutter https://gitlab.awi.de/paleodyn/fesom-mesh-generation.git
+```
+
+Note that you need to be working on `ollie.awi.de` and have the `cookiecutter`
+program installed (if it's not, try `pip install --user cookiecutter`)
+
+The program will generate a new directory with all the scripts and files needed
+to generate a FESOM Mesh based on the CORE2 resolution. After answering the
+questions the cookiecutter asks you; go to the newly created directory and
+simply run:
+
+```shell
+./run_all.py
+```
